Any chance of bringing a 'Mark User as Idiot' button onto the post profile panel? This would just build a list of 'people to avoid answering'. I've wasted dog knows how many hours trying to help this or that person, only to find that they post the same tired questions a few days later, not having bothered to respond. You know the type of user to whom I'm referring. Before deciding to give somebody a hand, I could check my 'idiot list'.
I know there's more to this than just helping the OP, etc. But seriously, could this be done? The profile panel of an idiot would then have some sort of icon (only visible to the idiot-applying user of course).
I suggested this some time ago, but only got a lukewarm reception. Has the climate changed since then?
