You broke the forum rules by the way,

* It's true you mentioned troll on the thread = action taken by moderators since it's against forum rules, thread moved into the trash.

* It's true you offer double Bitcoin and provided BTC address as well, we don't know what happens if someone sent Bitcoin by mistake = DT members (who left you negative feedback) think it's a potential scam method where is involved risk.

Moderator's action can't/will not undo, DT action would undo if you can only convince them. Anyone else couldn't remove your feedback.

Conclusion: A neutral feedback and report to the moderator were fine to me. Most likely I will not leave negative in this case since he mentioned "troll" in the thread.
