[SPAMMER DETECTED] user @arek only copies existing posts, yet @cheetah only flags half of them!

I just spent the last half hour downvoting and putting warnings on all posts by Hive account@arek as they're all copies of existing posts. Problem is that he sometimes copies only one line and a link, which apparently isn't enough for Hive account@cheetah to flag him.

What can we do about this? At 5 posts per hour, it's difficult keeping up with the flags. (it also means he doesn't know about the new 4 post limit, hehe)

Tips are very welcome!
