I'll move my post here too:

Although slightly off-topic here, I want to correct this misunderstanding: excluding someone from your Trust list can mean you 1. distrust their judgement on their Trust list, 2. distrust their judgement in their sent feedback, or 3. both.

This is really a wasp nest: it's virtually impossible to agree (or disagree) on someone's entire Trust list and all their sent feedback, so it's usually a compromise. It's probably best not to take this personally.
