When an OP is found out to be a troll, does an otherwise good question just disappear?

Recently, several interesting Q’s were posted on Fluther, and most of us gave good, genuine advice on them.

Then certain things started to look fishy, so the OP(s) were flagged. Currently, at least two of those Qs have been sent back for editing. The Qs themselves, and the answers the collective gave were good, and informative.

If a user is found out to be a troll, or is otherwise violating the site’s policy (regarding their identity, or age, or possibly gaming the system), does the Q get reposted? Or does it matter if the OP (rather than the quality of the Q) is suspended, or possibly expelled?
