You are free to have this leak but bear in mind, it's not mine, so don't bother me if the links/program/source/whatever stop working. I take no responsibility of this, use at your own risk.
I had no idea where to post this and if this has already been posted, I found a few methods to get a few Free Steamkeys, it are just a few games, not very expensive games, but atleast they're free! Got three two four methods for you!
I've been looking around for Free Steamkeys all around the internet, found a few websites which are pretty useful.
