Thank you so much for your generosity but can you please see the rules about random GA in this thread :p I bet there are more threads where you can donate keys :) Otherwise this thread will get way out of topic.
Also +1 ;) Zurvan7:
Only accepting gifts will be hard to find a trade :s Are you scared of the whole your steam account will get banned and keys bought with stolen CC thing (if I may ask?). Most bundle keys come from very well know websites...
If you only want gifts I suggest the Steam game specific trading section or steamtrades.com. You'll have more chance to make a deal I think.
I'd say GOG community is above other communities, but it's just my personal preference. I never trade keys, if I happen to get a key, and I do not want that game I will just gift it to someone.
I do use steamtrades.com. But, since its Summer Sale, and I can't afford games, I thought I could have more luck of finding a trade for those few gifts I have, if I post it somewhere else as well.
