There's this spammer, we all know him by now. Anyway, I checked to see his account, he's had one at ELU for the last 17 days. Why hasn't he been banned by now? I know that doesn't stop the person from setting up a new account but still... seventeen days, c'mon!
EDIT: I took a look in my flagging history, the guy has posted 9 times
EDIT 2 (28/5/2014): Only wanted to add that the flagging system is working a treat. Just now a spammer posted and he was annihilated within five minutes. Wow!
