Better spam bot protection?

[CodeGeek]

Hello everyone,

today it happened again: A whole command of spam bots entered AO. And it happens every few weeks. I'm wondering if there is any kind of (better) spam bot protection. And that's not a rhetorical question.
I can't remember the creation of my account here. But I guess there was some kind of CAPTCHA protection. But thanks to Captcha Brotherhood & Co. that's not a problem anymore.
Wasn't there also a confirmation mail? I guess that also no problem for these bots.

Any ideas? :huh:

because of the recent problems, one of the spam bots was removed as a test, it will be back in place soon
