Engage in transactions with others where you are being trusted by others, perform those transactions well, and if you impress people they'll leave you trust ratings.

Trust is largely overrated.

And don't ever ask for trust. If you do a few overzealous goons who've been here a long time will leave you negative trust for no fucking reason.

Also, regarding transactions don't try to offer escrow services, if you do the few (like 5) people who offer regular escrow services will talk shit to you and leave you negative trust simply because you're trying to be a new player in the market. The escrow industry on this forum, while legit, is literally a fucking racket. Collusion, etc.
