These sights that do brackets do give prizes for the winners. If they give you more than one bracket to win a prize why wouldn't you fill out more than one. OK, yes your chance of winning is basically 0% but who cares.

I look at it this way. If you were part of a raffle and could win some prizes and you were allowed to get 10 free raffle tickets would you only take one and berate everyone that took more than one. If it's free and if I could win a prize then I'm taking all 10 free raffle tickets.

Yes, I know that I could fill out 100 brackets and I would still not even get close to picking it correctly.

Just let people have fun the way they want. I honestly don't care how many brackets you fill out. If you only want to fill out one then good for you. It really doesn't matter me.

Sorry had to get that off my chest.
