Preventing Spam

[Bren2010]

I've been having allot of trouble with spammers lately. Does anyone know anything that can help?

Here are some of the ideas I've come up with:
Banned word list (my spammer apparently likes talking about sex. )
Preventing Proxies.
Banned user list

However, I need help with the first two. I could compile my own banned word list, but was wondering if there was a good one for download somewhere?

I already have some code in my .htaccess that is supposed to prevent proxies, but it only prevents some, how can I prevent them all?

You could take a look at wikimedia's spam blacklist here: http://meta.wikimedia.org/wiki/Spam_blacklist. You might also be interested in the massive categorized blacklist downloadable from page: http://urlblacklist.com/?sec=download. The latter comes with terms, domains, and urls. Both are regular expression based.

Why is this in Interpreted Languages? And what kind of spam are you talking about? Email or...?

[Bren2010]

Spam on my website. Comments, contact form.

I guess it was a bad choice of forum, but at the time I was thinking of making the solution with interpreted languages. Any way, in my defense, this thread is 3 months old! :p

Do you still have problems with this? If so, its actually quite trivial to implement a simple captcha system (or better yet, googles re-captcha).

Oh wow, sorry, I thought it said December 29th. My bad.

faazshift, It's not that kind of spam. It's a real person, not a bot. I know it's some pissed user from animalcrossingcommunity.com 'cause of something I did . Anyway, it's not as frequent any more, but it's still nice to have a filter in place.

fashizzlepop, no prop

Just block their IP. Solves the problem.

[Bren2010]

Did that. They used proxies, and since there's almost a million of them, it would be pretty hard to block them all. That's why I was looking for more/better ways.

Ah, so what about CAPTHCAs?
