Do you know of any good spam filters for Phpbb?

Do you know of any good spam filters for Phpbb? I am tired of manually deleting spam post on my forum.

Thanks for the help!

 

Do you allow guests to post. Or are spam bots registering?

Anyway, a CAPTCHA system should work.

 

CAPTCHA certainly won't -- or at least not for long.... Programers of spambots make new versions of spambots all the time, so you'd need to keep changing the CAPTCHA soft all the time...

Best bet is to install VBB instead of PHPBB - it's well worth its license fee

 

How will VBB fix the issue?

Anyway, enable CAPTCHA, and require email validation for registrations.

 

VBB has advanced protection measures. Apart of CAPTCHA it detects irregular visitors patterns (for example, in PHPBB many bots skip the registration page alltogether and directly feed information to the system -- VBB wouldn't allow that) and has multiple other ways of actually "recognizing" bots and denying them service. In comparison CAPTCHA is a very crude mechanism.

I speak from experience really, we tried multiple CAPTCHA software versions for PHPBB, some even worked... but only for a few months after their release. For spambot makers it's a full time job to find new protections and eliminate them, and they're pretty good at that. And for VBB makers it's a full time job to then make new protections against new versions of spambots, and they're damn good at that (that's why the free updates you get with the VBB license are important)

Our problems were completely solved after we switched to VBB, there's no more spam posts at all. Or rather, the spam that we do get is posted by humans.

And by the way, I complete forgot, there is actually a more or less efficient way to control spam on PHPBB -- Google up the "PHPBB Akismet mod" (Akismet is the same service that Wordpress uses to control spam). It's very efficient, but the downside is that it sometimes flags legitimate posts as spam, therefore potentially angering some posters and making the admin check the spam posts log.

 

There is a module where you can make the user answer a question. Eg. 1+1=2.
But the spam filter in phpbb is very bad, I prefer other systems such as Vbulletin(which is the king in BB)

 

Can anybody point me to any script?

I basically need some script that would allow me to approve members manually.

 

Afaik you can do that with PHPBB 3.0 Gold and there is also a PHP Akismet class on the net somewhere

 

There are many mods in phpbb for spam which you can find at there homepage. But you probably just need to update your version of phpbb.
