ok since it's pretty much clear that people manipulated now you should just use the comments, i don't think anyone will have a problem with it. and yes, changing ip is enough for that, my ip seems to change always when i have a disconnect (which happens often) and then i have to vote once more in those polls because otherwise i never see the results lol.
that's why "see results" is also a great option, you can use this then if you already voted once and want to be fair
