You could probably just post it here if you wanted to make it public, but if not theymos and/or Badbear would be your best bet.
Based on the other accusations that I have seen of people "abusing" the trust system, I would say there is a very good chance that the trust system is not actually being abused as the OP alleges.
I have also seen people claim that other are being "extorted" and "blackmailed" under the threat of negative trust when this was really not true as they did not understand the meaning of either.
This is something that should be made public if it is legit so the people who are making such "threats" can be called out if appropriate.
