Hello all,

Robots posting spam signups and messages are driving me insane. They signup using some sort of spam script I assume and post obscene messages, viagra and gambling messages.

Is there a quick change I can make to the UBB program files to stop these spam-bots? I would love some simple change in the signup and posting pages to make the spam-bots incompatible with my tweaked board.

Thanks for any assistance. If I figure out anything, I'll post it of course.

What version (and script) are you using?

First I'd make sure flood protection is turned on, then email verification is on for new registrations.

Hi AllenAyres,

Thanks for replying. I'm using UBB.classic 6.7.2 with flood protection on.

A lot of my members are very computer un-savvy, and they have trouble with the signup process. Quite unlike the skill-level of UBBDev members...so, email verification is beyond most of them.

Is there a change to the GET or POST line in a UBB script that will allow me to universally change the name of the "submit" variable involved, so that pre-made spam scripts fail?

Thanks for any help you can give.

Here, BTW, is a logfile of the attack, if that helps (note the 404 errors at the start)

hmmm.. email verification just sends the new users a link to click on, should be pretty simple if they are able to post in a forum smile Barring that about your only choice is to turn on registration moderation and approve each new user.

I'm not so sure about changing the post or get variables, everything is so interconnected. You may consider moving to threads, threads has an http referrer check that will only allow posts from within the actual forum, not sent from a spambot off-site

The main problem with Email verification these days are spam filters frown had to turn mine back on due to the script spammers as well.
