Winners have 7 days to activate their gift, but if I spot the winner online all the time and entering more giveaways without activating this to their account first, that's a blacklist.

Please set your profile and games to public if you win, so that I can properly check it before giving you the key.

I don't blacklist for not playing the games.

Edit: OK, stop leaving thank-you messages please, its not mandatory, not even for the winner. No harm done, but I literally cannot understand the logic of thanking every giveaway you enter.
