Those sites never works. Once you do that, it'll ask you to join/subscribe/follow all their 'profile' 'group' whatever.
Gleamio isn't fake nor a scam. However I would of recommended making a Private Giveaway on
SteamGifts at least for Game Giveaways. Most communities also use the Random.org technique where your post # on the OP / thread is your entry number.
Either or those are probably ways we can manage to do giveaways around here.
