Default So, 'smokes & the Admin posse...

  • Any continuity observed in the raft of spammers we have seen this past week?
  • Any proposal(s) on how we can thwart these dastardly fiends in the future?
I vote that we send them to Guantanamo Bay & make them write Visual Basic code for the remainder of their natural lives...

If we are getting spammed on a daily basis, we can turn on moderation of posts of new members.

That way posts of newly joined members will have to be approved by an administrator before they will be visible for on the board.After a new member has posted one or two approved messages, moderation can be turned off.

This is a slight inconvenience but if it will be explained as an anti-spam measure in the welcome message for new members, I don't think it will meet much resistance

IMHO, this WOULD be frustrating for new members. If you post something useful or ask for a solution, you want it to appear on the forums ASAP, not hours later.

Isn't it possible to automatically filter new members' posts for spam, block anything containing URLs or words related to the "sexology" and "pharmacology" jargons, and report them to an administrator?

Beastie, like a famous Dutch soccer coach said: "Each advantage has it's disadvantage"

The advantage of moderation is that the already joined members (the majoritiy) won't ever see any spam, while the newly joined members (a minority) experience a small lag before their post becomes visible.

Maybe CarpetSmoker, who is more familiar with the Vbulletin software,then me, could explain which other possible options would be.

Maybe it also helps to stop spam by blocking tinyurl's in the footer and the message self.

If you try to moderate only the first messages from a new member you cannot see the custom footer which can point to spam site with an tinyurl link.

For example see footer of nimbimumpipsy.

There are two things that first spring to mind:

o Update the forum, this hasn't been done in a while because it's quite some work to properly merge custom changed.

o Set some restrictions for new members such as inability to edit posts, larger delay between posts, etc. for new users (until they posted ~10 posts) -- This is what freebsd forums does for example, it doesn't stop spam, but it does make it harder for a single spambot to make 40 posts.

I don't have any time during the week, but I don't have any plans for the weekend .... Guess I just made some

I can relate to sending them to Guantanamo, but writing Visual Basic ... That just inhuman!

Can you modify the registration form? Some uniqueness will stop a few of the automated scripts.. perhaps have new users confirm their password three or four times instead of the default of two.

A little bit of PHP and HTML knowledge should be enough to find a way to break simple scripts.. the rest of the vermin can be squashed with Carpetsmoker's left boot.

We use ReCAPTCHA for the registration form, this is not something we need (Or can) update, since it's sourced from the ReCAPTCHA site and updated there.
AFAIK ReCAPCHA is one of the better CAPTCHA systems today.

Not really, many bots are pretty "generic" ... And there are also humans breaking CAPTCHAs for spambots.

What I would really like is a (basic) content-based spamfilter, something like this for example:
http://www.vbulletin.org/forum/showthread.php?t=131568

As a sidenote, in another thread (Can't remember which) and also in some post reports it was mentioned that this is starting to look like BSDForums, I can see where that is coming from, but I would like to note two key differences:

o Spam is actually being removed, note that on BSDForums the moderators has to individually move every single post a spammer made to a hidden forum called /dev/null -- So if a spambot posted 20 posts then they had to move 20 posts -- do'h! Even worse, they were unable to ban the spambot, there were spambots with hundreds of posts (I believe ocicat kept scores for a while).
On this forum an Admin just has to select one post from a spambot, opt to delete all posts made by this user and opt to ban the user, click on the button and it's done! Once a spambot is noticed it's a matter of seconds to clean it up.

o Things are being done to stop the spam from happening at all ... I know things are moving rather slowly, but at least they are moving.

Maybe this service is also useful, projecthoneypot.org.

If you search for 'projecthoneypot+vbulletin' you can find some good articles.

I know it's a chore, but I check every signup to fbsd forums against stopforumspam.com (well, not manually, a script). I usually nick 4-6 spammers a day, during registering.

Good tip Ben, I'll be sure to check that out!

You should be able to use stopforumspam.com fully automated, simple python/php/perl script to fetch all user registered in the last n hours, and then loop over them checking against http://www.stopforumspam.com/search?q=<QUERY>.

Yep, I just have that mailed to me. I use procmail to send assorted fields of the signup email from VB (New User email) to a script, which tags the username, email address and IP address with 'ok' or 'not ok', depending on the outcome of the query. The email itself should not contain '1 Jan 1980' as the birthday && '1' as the real name. That's a known bot -- block on sight.

We know you're trying your best, perhaps some of us are just recalling scaring memories from the past.

Take care.

@Carpetsmoker: SFS has a FF search engine plugin, very handy for quick lookups:

Thanks, but I don't use firefox.
