Re: Fighting spam bots

As an option to do a couple of questions during registration.
Very good idea to ban due to inactivity during the first day.

Re: Fighting spam bots

Maybe you want to look at http://www.google.com/recaptcha

It looks interesting to me. For example:

IP Address Detection

Our service also includes IP address filtering and detection. If we determine that a given IP address is successfully solving too many CAPTCHAs in a certain period of time, the address is immediately flagged for review. In addition, by providing CAPTCHA services to many customers we obtain a global view of spamming attacks, allowing us to react quickly to security threats.

If this software has helped you, consider getting your pro version. :)

Re: Fighting spam bots

I have updated the forum code and finally I installed reCAPTCHA mod.

Let's see now how this will affect activity of spammers.

Re: Fighting spam bots

Installed another mod: Spam IP Check - uses global black lists to prevent known spammers from registering.

Re: Fighting spam bots

How about using a graphical captcha (http://en.wikipedia.org/wiki/CAPTCHA) with distorted non-dictionary words and lines and other noise added to defeat machine-OCR attempts?

Re: Fighting spam bots

I think that probably we are talking about human spamers, in that case the captchas doesn't work.

I think the only way to get over them is some kind of confirmation MOD, but it's too much work only for Dennis, maybe if the rest of us (any "confirmed-people") could help...

Re: Fighting spam bots
