Technically yes, because it will appear as if you didn't activate your wins.

it's allowed, you will just get suspended/banned.

Don`t do that.

You won't get banned, but SG tool giveaways might kick you for not having them activated. There's literally no reason to remove games though... so just don't.

Hide them in your library if you like. Just don't delete them.

" I want to remove some games that I won on this site" so why you even enter giveaway if you dont want game? OK checked Country you dont need to respond i now know everything :D

If you want to remove them, why did you enter a giveaway for them in the first place? Oh, because free stuff? Of course, a free +1 never hurts.
