Or you could just toughen up your skin and ego and not leave negative feedback just because someone dared to say something you didn't like? Should trust abusers not be removed? It's a trust network and people are added and removed as appropriate. There's also nothing to stop you from getting put back on the trust list eventually (or even subsequently removed from it again), but going on about this over and over isn't going to do you any favours and if anything it will have more of a negative effect on your 'reputation' than merely being removed from default trust ever would. None of your feedback that you have built up has been effected anyway, just your ability to leave it and that was your own doing.
You keep saying it as if he just annoyed me a little... he was clearly there to harass me. If he was there to make a legitimate point about the product what were the insults for? Why continue on for post after post? He also claimed he deleted his posts, he deleted one then continued after it was made clear his presence was unwelcome.
The point is that the staff coerced a person whom you trust, and who trusted me, to remove me under threat of his own removal. He didn't remove me because he didn't trust me any more, he removed me because he was DIRECTED TO. That is clearly using the default trust as a punitive enforcement tool rather than what it was intended and purported to be - a way for users to comment on each other's reputation, practices, and behavior. Additionally its funny that some how I am trusted, but still I don't have enough authority to leave my own trust freely like everyone else here does default trust list or not. You preach to me about a single trust dispute yet you use the entire system itself as a cudgel to force trusted users to comply with your commands under threat of loss of their hard earned trust.
