Bottom line: You need to protect yourself, sold account or not, use your brain and don't rely on others telling you what to do. If you don't like the Trust system, don't use it. To say it is meaningless is, well, meaningless.
It is meaningless to me. How and why anybody would conduct any trades with anybody here they don't personally know is beyond me. Its just common sense to not trade with accounts here based on their trust rating since it is so easy to buy trust.
Same can be said for your position. After placing new rules to protect that are unenforceable, you now have a false sense of more security.
Well you can at least try to attempt to discourage people from being morally devoid, soulless pieces of shit.
