I don't think it's abuse. Now that it's been properly referenced I don't see any problem with it.
So you are saying we should start giving negative trust feedback to all dishonest members in this forum, or it's only ok to do this for Royse, call him names like ''crybaby'' ,mock him all the time, and talk with his customers/clients?
If the trust rating indicates PP's poor judgement then exclusion is the way to deal with it. But I don't think it's
abuse of the trust system, i.e. it doesn't really break any trust system rules or guidelines as far as I can see. Negative trust is for high risk, and PP stated as much in the feedback, and also created a thread to substantiate the claim (again, if you disagree with the facts/opinions/conclusions presented - that's a valid concern but I wouldn't call it abuse).
As I said in the other thread, I think contacting Royse777's clients is not cool, but as far as trust system is concerned, I wouldn't call it abuse unless PP said something like "if you do business with Royse777 I'll red-trust you".
I hope this is the last thread in the drama.
