I believe the trust system is good enough to heed as a warning. I know there's a warning for new users, but is there a warning for DefaultTrust negative rated users within the PM? If that's not implemented, that might be a good idea. I haven't got any PMS that I could check I don't believe, at least without digging. At the end of the day, even DefaultTrust has conflicting opinions on certain users, and I think having a warming within the PM area itself, is better than outright censoring a user who is viewed as untrustworthy by DefaultTrust.
