Have you tried contacting them about this first?
If you can't resolve this with bitpop, try contacting CanaryInTheMine about this as he is part of the DefaultTrust, and bitpop is on his Trust list. CanaryInTheMine doesn't seem to be a troll like bitpop so if the accusations are unfounded then he might decide to remove bitpop from his Trust list.
As for Goat, he is not a part of DefaultTrust, nor is he on a Trust list of any member of the DefaultTrust so if you'd like to have him remove the negative feedback, you will need to ask/negotiate with him to do so.
I don't troll that much, I contribute a lot (usually quietly) and don't scam. I'm honest as hell.
