The trust ratings of a staff member (DT) are not any different from other people's (DT) ratings. This system is independent from moderation, thus no ratings can be considered 'staff ratings' or 'official ratings'. They are personal ratings.
@moonpie45 - Giving -ve trust to account sellers became a hype only within this past few months and that does not include those persons above. You can read also that ratings/trust are put on as a "personal" thing. It is Lauda's or other DT's choice to give +ve or -ve to users,
it's personal.
