And in one fell swoop all 40 spam accounts are deleted. I wrote a script to delete any accounts with no followers or likes who only posted threads with links in them over the past 4 days. I'll put this on the crontab and that should make for a good temporary solution. There is a chance it'll catch a real account, so don't post links in your first post without earning some likes first.
Wow, they sure went overboard this time.. I'm going to write something to auto-delete this sort of account for now.
