    Most of these posts have come from an IP of 220.*.*.* with the second, third and fourth octet being unique. I also have members from Australia that have the same beginning 220 octet and if I ban all people with an IP that starts with 220 I will ban the people I want on my forum as well. I agree that this is not a solution.

    The bots/spammers also have joined with an address with a starting octet of 58 or 59. In the end I do not want to have to keep up with a huge list of numbers that I have banned.

    We have just been watching the forum and monitoring who joins and tries to edit their signature. We ban that person within minutes most times and although it is not the best solution, it is working for us.

        Suggestion: Semi-automatic 'quarantine' that misdirects the spammer or spambot.
        • I am just struggling to get a website and forum running and don't even know what Captcha is yet. (PS--oh yes, I guess Captcha is that image thing? Which I set to very low standards because otherwise I could hardly read it myself heh. Well now I guess there's no need to raise the standard.)
        • So I just came here searching for anti-spam tools because of being hit with annoying 'WOW GOLD' ads from lovebeijgo etc. Latest are loveumaryii and Dreamath.
        • I did not ban KaiyureBoy because there was no advertising. Just repeated messages saying 'I have read your article it was very helpful' and then asking for my MSN. I replied with a warning against repeat messages, and he stopped.
        • KaiyureBoy also did a 'fake signature' including 6 links for amateurish non-porn celebrity URLs. If that's all bot, it's a bit clever.
        • What I am hoping to find is some kind of anti-spam system that:
          1. Detects all 'probable spam' according to keywords which I can tweak.
          2. Display these all on one page. "Select all" and selectively de-select.
          3. In one action a) "Move all" spam messages to a spam archive thread, and b) "Quarantine" the transgressing members.


        By 'quarantine' I mean perhaps a permanent ban. But what might be better than to ban them: a) automatically move all their posts to an invisible subforum. Or b) automatically require that all their messages must be moderated before being posted. Thus, they 'think' they are still active members, and they do not bother to re-join under different names.

        [rant]These people are so clever with their software. And then so stupid to think anybody is going to reply to their WOW GOLD ads. Which doesn't even make any sense, in English at least. Yes and look out world, it's these brain damaged survivors of communism from Russia, China, and eastern Europe who are taking over the global economy. And America's answer so far is to elect and re-elect a born again Christian from Texas who can hardly get through a Sunday school reading. So we might not buy WOW GOLD but we did buy the gulf war II. Holy Toledo. Time to build bunkers.[/rant]

        The thread is located here.....

        ( Registration is required) He gets hate mail from the spammers along with expletives and threats but the list keeps growing

        http://www.vbulletin.org/forum/showthread.php?t=131568 I've added additional keywords to prevent our latest fiends from posting.
        I don't care that I need to delete and ban a few people each week.
        I'm just glad their posts are not visible. And I don't believe askimet is of any use. Look how much spam gets posted to vb.com.

        (False positives for 'hidden form' traps might come from blind people using aural readers...?)

          • 3.6.x


          I'm going to add my 2 cents to this thread as well. I bought 3.6.8 back last Dec. I've got a small, niche type forum so I don't get a lot of users or search bot traffic. In the last 6 months I've not had one spam attempt nor had I seen any guests that their IP addresses were from outside the US. And I keep a pretty close eye on my forum. I managed a much bigger vBulletin site for years that was constantly getting hit by spam bots and other unwanted attention, so I pretty much know what to look for and know just how bad it is out there.

          Come the end of May and I upgrade to 3.7.0. It hadn't even been up 12 hours and I get a Vietnamese and Chinese IP address. Next day it's Russian. A couple more Chinese and some small country that use to be part of the Soviet Block. Some of them just mill around like bots do and a few try to register, but so far none have been able to. So that at least is good.

          Sure, it could be a coincidence and I might had seen these had I stayed on 3.6.8. And that is what I would have thought had I not seen all the other threads on here about increased activity right after people upgraded. I read the comments that these people are targeting vBulletin 3.7. Maybe it's because it's brand new and since so many people are upgrading to it they want to see just how good it is...

          or maybe it's because they know that when people go to a new version they make mistakes and leave holes in their security. So the best time to try and take advantage is when people are installing new software.
          I was curious as to how easy it was to find out who was running vBulletin 3.7 so I did a Google search with the words "Powered by vBulletin® Version 3.7"... Yep, page after page after page of forums, including mine, came up. So for those wondering how they are finding out, it's not hard for them to find out who is on 3.7 at all. So vBulletin gets a lot of advertisement for free (that's just business of course) but there is a lighted path right back to all of us.

          I do wish that the US government would address the issue (or at least put more bite into what they are doing) of countries that allow (and in some cases are actively supporting) this type of activity. It's not just about spam anymore... most of it is targeted at identity theft and other criminal activities like that.

          I don't think the group at Jelsoft (or any other forum software) will ever be able to create the perfect forum software. It's always been known that anything one person can create, another person can find a way around. It's the nature of the beast and one of the costs of us wanting to run forums. I think Jelsoft does a pretty good job and I hope they continue to stay close, even if they can't get ahead of the people that are out to take advantage of us.

                      I'm afraid the answer was:

                      "There are as yet no confirmed and verifiable reports of this happening."

                        To clarify I am talking about Bots bypassing the registration and verification process. As long as you allow registration there is nothing to stop humans from registering and then turning over the account to a Bot.
