Credibility of these sites

[camlei]

Im new to this thing and i just received some links:

www.4freespot.com
http://compstuff4free.com/
http://www.freemacgifts.com/
http://www.get4friends.com/

i live in canada so i cannot participate in the regular channels such as freeipod.com

so i was wondering if anyone participated in any of these sites, and if they are worth trying out, cause these are ones that i found that work for canada
