Whats with all the referalls links I've been seeing around here?

No. It does not work. The people posting them are dumbasses who have been deluded into thinking it will work.

Hi. I'm new here. Can I haz free gaemz?

If by "work" you mean "end up with your Steamgifts account suspended", then yes: it's very effective.

If you're planning on acting nefariously, there are definitely better ways and better places to do it.

It probably does work, but the amount of work required wouldn't be worth it. In order for them to give a free $50 game, the owner of the website would have to make $100-$200 off you (survey's, trials, etc).
