We’re fighting the good fight and doing the best we can. I’d say overall it’s going pretty well. Every bit of spam is blacklisted by IP forever, so that definitely helps over time. People can’t sign up unless they do a captcha AND click a link in an email, so it’s gotta be real humans doing most of it.
Since the upgrade, there have been 12,000 (!) attempted spam accounts, and only a handful get through, so I think we’re doing a pretty decent job. If people ever catch a nasty one, you can always email me directly at [email protected] and I’ll go zap it right away.
