Please be aware that anyone sending you a link containing "steampoweredgifts" is a scam, and they have most likely been infected by this scam too. They claim to be giving you free steam games, and sends you to a steam look-a-like site. Then it tells you to login with your info and choose some games. I looked into the source and suspected a scam, so i made a fake steam account, and without suprise, they took the account .
The reason i know this is a scam is by looking into the source code. Instead of giving you free games, it sends your account details to a server. What a nice christmas present!
