A good indicator for
Trust Selfscratching is to check the "Untrusted feedback" for a DT1-member. If there are much less untrusted than trusted feedbacks, it's likely the user is raising his own Trust score by including them.
They're also easy to find by checking who put the youngest users on DT2:
Users can add whomever they want to their trust lists although they should be a little more strict if they're DT.
That's true, but if enough people include users for the wrong reasons, DT becomes even more meaningless.
Don't forget:
Trust list
List the users who you trust to have good trust ratings and good trust lists
I could increase my Trust rating by about
+35 if I'd include everyone who left me feedback, but if I'd do that, others should exclude me for using the Trust system incorrectly.
Especially on the Collectibles board, the Trust system is often used incorrectly. This has been going on for years, and I expect it to continue for years too. It's not even that terrible anyway: it's not as if they're using it to scam others.
