Post isn't belongs to Reputation, I think meta will be appropriate.
If you think that a ban should be ended, make your case in a new topic from a "good for the forum as a whole" perspective.
Not sure admin will reconsider or not but you can try.
i beleive in the good connections established between DTs and Mods. I also think it's a reputation case.
Ban account really not connected with DT network. Only admin could help about banned account.
