I understand positive feedback & its effect on a profile but How does negative feedback work?
Using this profile as an example:
brendanjhwu
-8: -3 / +0
How do these negative numbers behave differently if the profile does/does not have Default trust in their trust settings?
All I fully understand at the moment is the middle number is the number of unique members who have given this user a negative feedback within his/her trust list.
Almost correct. It's the number of unique members who are in your
trust network. Not having Default trust in your trust list will remove everyone that was added on DT from your trust network. Adding other user in your trust list will add them, and the users in their trust list if you set the depth to 1 and the users in depth 1 users' trust lists if you set it it to depth 2 and so on, to your trust network.
The number on the right is the positive feedbacks and works the same way as above.
First number is the calculated value of the other two. It is quite complicated for me to explain properly so I'll just refer you to the
formula here.
