What in the hell?!?

Ok, so I included a poll in my next update. But, I marked the update that the poll's in as 'Hidden'. I just checked the reults of the poll expecting them to be all at 0. But, somehow my secret poll had results!!! How is that possible! I haven't updated yet!! How does that work? Can anybody else see my poll? How does the 'Poll of the day' work as well? Because I've seen that AFF changes out polls. 

Can somebody please explain to me how people can see a poll that I haven't put out yet?
