    I typed russia in the seach on this forum and got this thread right away.

    I have been getting hammered also, deleting them as they happen.

    What I noticed that was constant is the time zone in the user area once they joined. (GMT - 12:00) Eniwetok, Kwajalein this was on every single one so that's how I sorted the good from the bad.

    I just added the extra question so we will se how that goes.
    Mine all register with a Beijing time zone. I run a private gaming site (started with EQ, now it's warhammer) and the majority of my spams have been gold sellers for the online games, with the occasional viagra or porn thrown in.

    Months ago I thought that there was a bug in it but the answer was that it was not a bug,it has been designed that way.

    Nospam question: This forum's name is v***letin
    Answer:bul

    Giving the answer "bull" :rejects it

    Human Verification [email protected] question:This forum's name is v***letin
    Answer:bul

    Giving the answer "bull,bulk,bulldozer":happily accepted.
    That would only happen if you put "bul" into the regex option as is. If you want to only accept "bul" then create a proper answer using the answer system. If you want to use the regex option then you need to understand how it works.

    My site got hit as well. Thanks to everyone for all the tips. By enabling all the image options and adding a profile question I was able to stop the spammers (so far).

    One thing I noticed which may help others sort out spammers from legitimate registrations. The spammer accounts were all different but seemed to have one feature in common, they all had the time zone set to "(GMT -12:00) Eniwetok, Kwajalien". That is the first time zone in the list and a pretty unusual choice since it is in the middle of the Pacific ocean. So you might want to ban or delete any new members set for that time zone.

    Yes.
    Default usergroup: always moderate new content
    New usergroup: additional usergroup with same permissions, except now do not moderate.
    New promotion, based on default usergroup, based on 2 or 5 approved posts, to upgrade to additional usergroup to get proper permissions.

    Now all new registered users posts are moderated, upon approval, their postcount increases, when over a certain amount, the script auto updates them, so future posts dont need to be moderated.

    Well I made questions in the manner: "which is the main city of our country"
    "which is the highest mountain in our country"... So far it seems to work

    Also - is there (if not it would be welcome) an option to put new posts into moderation, until admin approved them (or moderator).

    Yes, but might be tough on the non-english speakers of course.
    And no, because once the scripts support live translation, it might not work.

    A simple question can still be asked in a creative manner that makes it easy for a human to rationalize, while it's garbage to the bot.

    Same here, before 2 days we had at least 15 new spam registrations.

    Now we put Q+A.

    I have question on that. If we made simple questions, but are on foreign language (not english, german, spanish, italian...), this should prevent far "english speaking spammers) shouldnt it?

    Thanks Floris.


    Ok to those who suggested banning email extensions such as gmail.com, hotmail,com, etc...... give it up, imo.

    It's not going to work when you have a site like this - email.com. Here, my friends, you can register an email address with an extension of email.com or mail.com OR..... any other of thousands of email extensions. Take a peek. Click on the link that says Get Your FREE Email Account here.

    So if you ban one extension, they'll just go get another. It's a losing battle

    Change from the image to the Q+A method. I've linked to suggestions earlier in this thread I believe.

    Thanks Floris, but it's not guests that are spamming me, it's new registrants.
    I've been using Human Verification for quite some time now. They got past that a couple of days ago.

    Mass inline options for the admincp is what I recommended in the past and revisited yesterday. You can turn off the contact us form for guests. And you can set it yes for guests, and use the HV as requirements. Make sure the usergroup has the permission set to yes for 'use HV?'

    HV = human verification ..

    So far I've not been able to stop registrations with ANY method mentioned here, but I have been able to keep them from posting on the forums with moderation.
    My spammers are from everywhere - assuming of course that they're being honest about location, lol.

    I had over 100 new registrations just last night. I really REALLY wish the devs would develope a way to MASS delete users, the same way we can threads. This having to delete them one at a time is ridiculous.

    Now they're spamming me using the Contact Us form. grrrrrrrrrrrrrr....

    Spam Messages

    Like everyone else, it seems, I'm having serious trouble with vicious and obnoxious spam, which has recently become a real problem and is threatening our on-line business.

    I've switched to manual verification on top if the usual visual, plus e-mail verify, which is a real pain and expense but looks like the only way for now.

    As we are a specialised professional site our users don't appreciate the spam, especially as some receive it automatically through our RSS feed - quite embarrassing really.

    I'm therefore considering going to a member only registration system for use of the forum:

    We'll have a site registration system where members will give full details (name. address, location, company etc) to be stored in our MySQL data base

    They will be given a unique Membership number, plus they will choose a user name and password, the latter two to be used for registration and forum posts.

    Can anyone think of a way I can proceed to restrict registrations on the forum to these registered members, ideally also incorporating their unique membership number when registering / posting? This should give a really secure forum in my view?

    Also, I notice that ALL the Spam posts are coming from one particular time zone - Asia / Russia

    It would be ideal if on manual registration it would be possible to segregate registrations into time zones - one for our own (UK) where 99% of our users reside, and other zones.

    Also, would it be possible to search the forum for time zones to locate any existing spam posts which have already slipped through?

    Would all this be possible?
