It started as a trickle once before on a forum that I help maintain and turned into a flood as our forum was added to a list that was used by spammers. We upgraded our software, and the spam stopped dead. Well, over the last few weeks it started raining again.
Apparently both PHPBB and gmail’s captcha’s have been compromised, so soon the rain might turn into a flood.
Google needs to address this yesterday, heck even turn off new registrations until it is sorted if they have to.
Interestingly, an akismet type approach may be the best way in the long run instead of the poorusability that is a captcha.
