I can't speak to the rest but personally I find the poll system infuriating.  I cannot, personally, seem to edit a poll and make any sense of the answer if people have already voted in the poll.  If I delete a field then the results of the next field appear where that question used to be.  You are saying he deliberately deleted a poll result and the next higher result showed up?  Or did he change the context of a poll by changing the words?
