  • 95% of the spammer usernames/emails that people here have mentioned so far, I too have come across. I noticed in late May that the birth date was the most common factor, but I have a feeling that the more we talk about it, or the sooner we come up with an automated solution based on the birth date...

    the sooner the spambots will either stop using that birthdate, or start using random birth dates. We should assume the worst - that we can't count on this birth date red flag, for forever.

    Nearly every time a new spambot (or a revisit of an old spambot) appears on my site, I've manually ISP blocked it, which involves a WHOIS to find the complete IP range.

    I have to be very careful when I do this, because although my site is English language, it attracts legitimate users from all over the world - including a few from China. So every time I ISP block another Chinese range, I always check it against the very few legitimate Chinese members my site already has. This tactic will eventually stop another legitimate Chinese user from joining my site, but the spam is so out-of-hand right now, that I'm considering this to be a small price to pay. I don't feel comfortable with ISP blocking as a longterm solution though.

    I'm probably going to introduce a subforum for New Member Introductions. When you confirm your email address for registration, you're shifted into a phase-one custom usergroup that can only post, in the manner of starting new thread(s) in New Member Introductions. Until you've done this, you can't start threads in any other subforums, or reply to any threads other than your own. After that, if you have at least one post, eventually you get auto-promoted, and can post/reply in any subforum. However, that promotion could come real quick, so to make sure it's always at least an hour, you introduce another intermediary custom usergroup, whose sole purpose is to exist one hour before the promotions CRON triggers again.

    Once a spammer starts posting, they'll do it in waves. They aren't going to sit around and wait 1-2 hours until they can post in other subforums, and that's if they're not banned by then. What I like about the New Member Introductions idea, is that all of the spam will originate in one place, and you can safely appoint a legion of moderators solely for that board, with custom permissions so they can only move posts, and you have a trash/spam subforum that's not public, as evidence for a higher-up staff member to eventually issue a banning.

    I can understand why some vB owners here would want to block their Member Lists, because a little-talked-about problem right now, is spam across Private Messages. Though I don't know how much good it does to block the Member List, because a smart spambot could build its own index of usernames, by brute forcing all of the User ID numbers. I'm thinking of reserving the Private Messaging privilege for users who have already posted at least 10 times, and same with being able to view the Member List or any individual User Profile. That ought to solve some problems.

    Now, I'm not deeply knowledgeable about the repercussions with robots.txt, so for anyone who is more familiar with how it works, will spambots being able to access robots.txt, in any way foil any of my ideas here?

        Notes: They used the Contact Administrator form, after they were banned. It was an admittance that what they would post if I unbanned them now, would have the same problem as before - "free iPods" are not what my community is about.

        Some Chinese/Russian spammers are going to slip through the cracks I've left open, because I've limited some of the ISP blocking for a few of my legitimate users, and a minority of the spammers may fall within that range.

        • Beijboy/girl et al

          We've had the same as described in this thread.

          Running 3.6.8. with True Type font etc etc etc... I did raise the point in another thread a while back that spammers are getting around True Type Font Captcha in Vb.

          I delete the spammer just as soon as it appears, often within a few hours (our email notifications are often date stamped around 3am UK time).
          Again, we just keep blacklisting the ISP (and its wildcard string).

          We've had the whole range of Beijboy from 1-5 and other such like. Clearly, using the username vbulletingirl/boy he appears to like vb forums - we've had those too. Thankfully, the spammer only managed to post on one occasion - they seem to like placing advertising links spread across the forum. Ours was for some pc game. I am of the belief this is a wannabe spammer - probably contracted by some US spammer.

          Yes, there is a pattern: the birthday remains the same (01 Jan 1980) as does the time zone: hong kong, singapore etc. In my experience the spambot registers, and then comes back a couple of days later to post the links.

          I think the following link is the real Beijboy from a couple of years back, username: Beijboy - a student! Are we surprised? Perhaps someone could reply to him to be his friend!

          The outcome of this is that Gmail along with the most frequently used ISPs have been blacklisted. Unfortunate, as we too see some user-traffic from China. But we can do without this. I simply put a notice below the email entry in the registration form (confirm email string) that users wishing to register using a gmail address should contact us first. A hassle, but much better than spam littering your forum.

          On some other non-forum websites I operate, I am also seeing an increase in gmail spam. It's coming from China, Vietnam and South Korea. Google have still not addressed their security issues and spammers are getting hold of email accounts far too easily. Gmail has been banned on all my other sites.

            Free email is free email. I doubt Google does any checking on signups on their system or the emails that are sent out until someone complains about a particular account. Just not enough man-power in the world for that kind of moderation.

            I have a GMail account and it gets about 1000 spam emails a day from Chinese accounts. One of the reasons I don't like the service.

            • Thanks Wayne.

              And that's why Gmail will remained blacklisted on our site, and every other site I operate.

              Life was so much better with Compuserve in the early days - if not a tad expensive!

                • I still get a LOT of badguys using yahoo.com so its not just a gmail issue but then again I get a lot of .ru, .qawab, .info and sina. Beijboy uses sina email addresses as frequently as he does he does gmail, fyi. Many of the post in this thread act like the whole concept of "Asian Market" doesn't exist any maybe it doesn't if your are running a custom home entertainment site in St Joseph, MO but the reality is quite different. I have multiple sites that target the Asian Market so banning blocks of Asian IP address, Chinese or otherwise is not really an option. I still think that a dedicated effort by Jelsoft to find out how this particular group of badguys seem to be able to completely bypass the human verification process that doesn't see to work or is simply being hijacked by their robot code.

                  • I got a lot of gmail spammers also.. I never had those guys and now they seem to pup up every day.

                    I use a system of Captcha and questions like 1+1=, they still manage to get through.
                    And like I've said: mostly gmail, since they beat gmail and hotmail it's amazing how many accounts are being abused.

                        Rather than banning all of China (and Russia) outright, I've waited until more spambots have shown up, then I blocked whatever new ISP they use, with small holes deliberately left open so my legitimate users can get through. If you don't think you'll ever have legitimate users from China, you can tweak my list a little bit, but don't go overboard on wildcards to 'optimize' it, or else you may not only be blocking ISPs that spammers have never targeted a messageboard with, but the ISPs may not even belong to China or Russia.

                        So far my ISP blocking (as is), has prevented at least three spambot registrations per day, and that seems to be all there is. I've been "Viewing Who's Online" and I know what their User Agent looks like. I've updated my list before some of them (who weren't blocked before) had gone through captcha.

                        Don't be hamfisted with the ISP blocks. Check the prefix numbers against existing users, some of whom you may not already realize are Chinese, and leave holes open where necessary. For example, if

                        221.216.
                        221.217.
                        221.218.
                        221.219.
                        221.220.
                        221.221.
                        221.222.
                        221.223.

                        represents an overall ISP that a spambot has used, and if I have legitimate members with

                        221.217.222.
                        221.217.223.
                        221.217.224.

                        and

                        221.221.244.
                        221.221.245.
                        221.221.246.
                        221.221.247.
                        221.221.248.


                        then my actual list as you know it, has very carefully used wildcards with specific suffixes to allow these two users through.

                        Never forget that a wildcard of 221.221.24*, will block 221.221.24. in addition to 221.221.240. through 221.221.249., or else in other examples you will eventually block some Australians without even knowing it. Don't use it just as a routine convenience tool to avoid typing in more numbers, and don't just automatically ban the first two-to-three numbers everytime a new spammer shows up. Always WHOIS them first, and find out what the whole IP range actually is. Sometimes even a last-suffix ban can be hamfisted, because you'll have a proxy company in the middle of Europe, surrounded by legitimate ISPs.

                        Notice the 82.128.23.0 I have on my list? If I didn't include that zero on the end, I would actually be blocking some users of another ISP, because that zero is literally where this particular company's IP range ends, instead of simply at 82.128.22.255.

                        My list isn't perfect, and more will probably be added to it eventually, but in the meantime I know it's working very well, even with the holes.

                            Have you noticed any performance impact with a list t his long? My list is only about 2 dozen IP's long right now, but China and Russia are big places.

                            I've got a fairly nitch forum and most of my users are going to come from the US, Canada mostly, with some from England and Northern Europe. So I'm not all that concerned about banning the rest of the world. I'm going to put up a message for the very rare IP that gets caught and tell them why it's blocked and to send me e-mail (at a throw-away e-mail address) to let me know.

                            It's too bad you can't have exceptions to a range. That way you could ban a whole sub-net and put a exception for the few that might be valid in that sub-net.

                            Since I went to 3.7.x I've been getting about 6 Chinese, a couple of Russian and one or two odd other countries every night about 10:30 pm Pacific time that I ban the IP groups on. But so far (knock on my lucky 286 chip), nobody has made it through. A lot of Registering but they never actually get registered.

                            • We too see this problem increasing at an astronomical rate. However we have only been spammed twice since 3.7 came out. That was when we left the bot member in "awaiting email confirmation" status and 2 or 3 days later they came back and spammed.

                              I have now made my Super Moderators "limited" Admins so they can delete members. As soon as we see the "awaiting email confirmation" status, we delete them after 24 hours.

                              We also put some required fields in their profile screen. Funny thing thing is, they fill them all out correctly, except that they are always the same. First name = 1. Location = 1. Birthday = Jan 1, 1980. Gender = alternates between "F" and "M".

                              Captcha and ReCaptcha are USELESS!

                              I also tried the Q & A scenario. Question "twelve * three + 1 = ?" Unbelievably they either get the correct answer, or bypass it completely.

                              Some how, vBulletin must have a "huge" hole in it's whole registration process. What else could it be?

                              This whole situation is just crazy!!!

                                It could be that a human registered for an account, then pass it to a bot to post.
