Any new accounts that posted spam have now been suspended, and new accounts that haven't introduced themselves (<waves hi to zac>) have been silenced.
If you have been silenced but are in fact not a bot, please ask @woozle to un-silence you.
We'll continue silencing new accounts that follow the patterns I've noticed.
Everyone else: please do report any spam you're still seeing.
Thanks, everyone, and sorry for the nuisance!
