As you can see in the screen-shot below a user posted the same question again and again.
Those questions showed up on the front page of tor.stackexchange.com and did not go away until enough users down-voted them or flagged them. (This took far too long for my taste.)
How can we brush them under the rock faster?
The user did not even try to flood this Q&A... I imagine how nice it will be if someone of some dudes actually try this. This could use some rate-limiting, especially when some user has only questions/answers with negative score (or only negative votes) and a reputability of 1.
