He has one trusted negative feedback (from Mabsark) and no untrusted feedback. Why is he in level 2?
If you look at hierarchical view of trust, it appears that both der_troll and Mabsark are listed under CanaryInTheMine, who is level 1 default.
If Canary includes der_troll in his trust list, but doesn't leave a feedback for him, would that add him to the level 2 list?
Edit: saw BadBear's post. It would seem so.
You don't need to leave someone feedback to have them on your trust list.
