Spammers tend to come in clusters...

Probably a spammer put us on his list and has a botnet doing his dirty work. Different IP on each one.
I've been lazy but what I really need to do is create tiered access levels, where new users can ONLY make plain posts without links until approved by admin or maybe until enough posts. That'll help, especially with the various little places I don't remember to look for spam so often.
