I'm sorry but you kinda twisted things with that double negative. What i meant is that is very easy to fake vouches and really hard to verify them.
For example, i can make up vouches for myself, how are you going to verify is that is true or not? You can't. I can just make them up or i can ask some friends to vouch for me and when someone ask to them they say "yea he is legit" and so on... now, when someone say that vouched people are 100% trustable i can do nothing else than crack up here. And that was my point... that someone who is a long time player, known, who have purchased many UGC's already and has no scam report under his name is is way more "trustable" than some random guy with a 0/8 wizard and a 1000+ vouch list.
