Tomatocage is well known for leaving feedback if he strongly suspects someone of being a scammer.

However, of course this does in no way mean you are. It just means you would have to show that you aren't in order to get the negative trust removed. I feel for you if it was unjustly given, however Tomatocage normally does justify why he leaves negative trust, so there must be some reason he chose to leave it?

Some context would be useful.
