I really am getting tired of 30% of my bandwidth being given to spammers and they mostly come from India. I know there are many English speakers over there but I'm just so sick of seeing 200+ users registered every day from spam. Maybe a better approach would be to force a administrative OK if they register from India?
I don't know, I'm out of options, I've tried various captcha's they just won't stop. Banning their IP's, emails, and usernames does nothing and it can only negatively affect the innocent if the odds are good enough.
What have you guys done that worked against spammers? These aren't spambots, just a bunch of spam-monkeys registering away.
