In this post, lolgaxe made a poll for the OP. I voted in the poll and moved on to the other posts in the thread. When I reached the bottom, I scrolled back up and was overcome with the urge to rate gaxe up, and so I did.
When I rated him up, the poll reset from the 'results' view to the 'vote' view. I was able to vote in the same poll twice... IM IN UR POLL, SKEWING UR TALLY.
