That's what usually happens once someone who's left a lot of negs makes it to at least DT2.  Their inboxes start getting flooded with pleas for mercy, etc., and you start seeing threads like these.  It's all good if the person who left the neg doesn't have any power, but once they do....watch out.

In any case, OP there's nothing the community can do to help you with the feedback that was left--that's an issue between you and JollyGood, and just glancing at your feedback, I'm not even familiar with that particular drama episode.  If that project was legitimately not a scam, you might have a good case if JollyGood agrees, but there isn't anything the rest of us can do.
