Can one flag a user, or only his/her posts?
I have seen several posts that I wanted to vote down, and noticed they were from the same user. Checking their user page, I notice that of the 7 questions asked (all in a 5 hour time period) 5 have been voted down or closed. I have a sneaking suspicion that this user is hoping for a prize in the contest, and thus asking whatever they can think of.
I am not saying this particular user should be reported per se (hence my not naming them), but it did lead me to wonder whether there is a mechanism in place for reporting a user who consistently does not 'play by the rules' (nasty comments, subjective questions etc). Perhaps a temporary posting stop or something similar? I don't believe one can actually ignore a user, only tags.
