I know that all your trying to do here is to say thank you to your followers, but asking for an up vote in order to participate in the "giveaway" is widely considered as vote buying, therefore you could end up getting flagged for this, I'd personally suggest a change in the rules of the giveaway so that it doesn't require an up vote to participate. I also have suggested a different solution on this in my last post, if you want you can check it out. Hope it helps, cheers!
