User blog comment:Sannse/Blocking Best Practices/@comment-1709282-20121010014844

You didn't mention spam. I used to have to delete pages written in Russian hawking knock-off Viagra quite often. I'd always block the people that created them for 3 days and most of them never came back after that (they'd get blocked for longer if they did). Come to think of it, I haven't seen any pages like that for about 18 months. I guess the spammers have gone elsewhere.
