People that spam cell phones

[keithsl]

I was just wondering if anyone else has this problem. We have these people that join our forums a couple times a week and spams advertisements for cell phones. I'm pretty sure they're manually registering but I'm not sure. They usually only spam a message or two and then leave.

I'm running 3.6.0 btw and I added a bunch of fonts to the captcha.

Anyone else have the same kind of stuff? I googled one of the phone numbers they left and found a lot of spam with the same number: http://www.google.com/search?q=447023051282

Anyway I was just mainly wondering if they're doing this manually or not.
