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.
