USTA quite is like the "mafia".
There is (still) a lot more "human influence" than I think is needed. I understand the importance of a human "override" but its ability to be abused is still there.
I've seen really strange things happen within the USTA and these things are not just NTRP related.
The only thing I can tell you is to "challenge" the DQ. A lot of these "section heroes" will do whatever they want because they are often not challenged. Think of it as a cop potentially abusing his/her power. Take it to the "internal affairs" department, or even higher if needed.
"League admins" and "higher" are closed circle groups.
