No i don't have anything special in my trust settings it seems that profile's negative feed backs visible only to above 480 activity, you are only 18 points away from to get this
Wrong. There is no correlation with seeing negative feedback and 480 activity.
For me he is: Trust: 10: -0 / +1
I would also advise you to keep the default trust depth where it is. Ratings from members on depth 3 or 4 shouldn't matter to anyone.
And thats the problem, we should see all trust ratings like the same, some people shouldnt have more weight than others just because the sake of it.
The real problem is that you don't understand why yours is a really
bad idea.
If all ratings weighed the same, anyone could just push their trust score to huge levels by creating fake accounts and leaving positive feedback.
It is a very bad idea. That would be so much prone to abuse and we couldn't trust anyone or anything by then.
The system in place is decent, and nothing better has been suggested so far, thus is is the (currently) best solution.
