Vouches do their job. Sure someone can vouch for their friend, BUT, a smart buyer would look through someone's vouches, clicking on a few. Looking around and seeing if the people who vouched for the seller are legit, trusted, ect themselves. It's easy to find fake vouches or vouches from friends. Basically your idea is to have the vouching system all over again, except that we don't have the ability to dive deeper into a user's trust on sythe, and fish out possible scammers. Besides, do we really need another user-friendly website? That takes the fun out of everything.
