He currently has +42 positive DT-feedbacks, and if I exclude him to see the difference (don't test this on a DT1-account!), he has only +7 left.
I think this change is the main indicator of probable abuse by DT1 members.
Besides requiring more than one DT1 user to add someone as DT2, this suggestion of mine could solve this potential abuse:
If a DT2 member is added only by one DT1 user and the former left positive trust to the later then it should not appear as trusted on the DT1's profile.
So in practice the DT1's default trust should not be affected by changes made by that DT1 user to their trust list.
What does the 42x mean next to dabs?
If I understood it correctly it means he's added 42 users who have left positive trust to him, regardless of whether other DT1 users have added them too.
In dabs' particular case it seems almost all of them became DT2 only because of him.
Edit:nearly 100% of deals conducted between those in the list are conducted without escrow - the level of trust there is fucking strong
Trusting someone is not reason enough to add them to the trust list (despite the name).
We must add people to the trust list if we think the feedback left by those users is useful and fair. And it must be useful for most if we're DT1.
If someone is extremely trustworthy then they must have dark green trust but not necessarily be on other people's trust list, unless they also leave proper, useful feedback.
