Many new users (bots?)

Hello,

I have about 2-10 new users everyday that are suspicious. Every user is the same in that the username is gibberish and usually their email address comes from russia or china. These users haven't done anything on my site yet (I delete them right away) but they do fill out a portion of their profile (AIM information). Is it possible that this is from an automated bot? Maybe I should install captcha. Is it possible to install captcha only for registrations?

Mollom

Sure sounds like a bot to me.

I'd certainly recommend Mollom -- I've had less than 1% of the spam on my site make it through their filters. Mollom provides protection via CAPTCHA on user creation screens, but on regular content it analyzes the content and only presents the CAPTCHA if the content looks suspicious (thus there's no intrusion presented to most people most of the time -- nice!).

How long have you used Mollom?

Jason,

How long have you used Mollom? Also, are you using the free subscription or do you have a paid subscription?

I've considered using Mollom but have been a little leery because of rumors of buggy code. Have you had any problems?

Thanks,
Curt

That's one of the rumors I mentioned. However, that really doesn't give very much information to use for an informed decision.

Ok. Thanks for the comments.

Ok. Thanks for the comments. I am going to install the captcha module and only set it up for the registration form. Let's see how this works.

well I installed captcha but

well I installed captcha but I get a message saying that my version of PHP doesn't support truetype fonts and the bitmap ones look wierd so I am only doing the math captcha and it's not effective. Assuming that the new users are bots the math captcha is not working :( New bogus users have reduced a bit as I only get 1 or 2 new bogus users a day now instead of the 5-6 I was getting before but I am hoping for something better. If the word captcha much more effective than the math captcha?

reCAPTCHA

You might want to give reCAPTCHA a try. I don't believe that it should have any dependencies upon PHP for image creation.

Good luck,
Curt
