A user just applied an edit that was completely trivial (arguably harmful infact) specifically for the purposes of increasing the visibility of the (now quite old) question for extra rep. They actually put that as the edit reason.
I rolled back the edit, naturally. But how should one deal with the problem of the behaviour itself? My rollback simply bumps the question further, which rewards the behaviour. Is it even a problem at all, or are karma-seeking bumps like this ok? Should the question be flagged? If so, what action should the responding moderator (assuming they agree that the behaviour is wrong) take? Can we only take action in cases so blatant as this one, or would a repeated pattern of small edits by a user to their own question also be enough to trigger some action against them?
