I am not sure where you got 25 from.

In order to be on DT1, you must be trusted by 10 people with at least 10 merit, one of which must have 250 merit, both ignoring merit sent by the person, assuming you are not blacklisted by theymos.

Only one person needs to be convinced, theymos, as he can blacklist suchmoon from being on DT1. Otherwise, 15 people will need to remove suchmoon from their trust lists.

It would probably be best for her not to be in a position of authority, as she appears to always side with those with more power in disputes. Also, she does not appear to have any kind of trading history, nor currently is active in trading, which effectively removes any consequences to her receiving any retaliatory ratings.
