He tried to damage my reputation, So I can say in that way it comes under the 2nd category.
Many have tried to damage reputations of others around here, and many have failed. Timelord2067's review is not trusted, so it really doesn't mean much. It would be pretty hard to justify the claim that it cost you potential income, and impossible to prove that any agreement was implied. That's not proper justification for a flag, and if you create a flag under that premise then you are abusing the system.
I've read your justification for using that address, and I believe you. The best thing to do at this point is for both you and Timelord2067 to remove your feedback. You left feedback for retaliatory purposes, which I think is wrong in the first place. Perhaps by rationally discussing the situation with Timelord2067 in PM you can convince him to remove his feedback.
