I'm curious how this works, now. What are the first two numbers actually referencing? gmaxwell is +205 and still red to me.
If you bring up the trust settings you'll see at the bottom the list of people who's ratings you're picking up. Nested under each person is the transitive ratings.
If you just trust the default trust group at the default trust depth I won't be red, because the only person distrusting me (Goat) is 3 levels down from there (the group counts as a level). If, instead or addition, you trust (say) Theymos directly then Goat will be two levels down (via DeaDTerra) and his ratings will be included. If instead of trusting Theymos you trust Maged then Theymos and his parties will be included transitively, but Goat will— again— be three levels down and won't be included and I won't be red.
Make sense?
All the trust flows along the configured trusts lists, it's orthogonal to the ratings. But there is no way to filter beyond the global depth. So you can't say "I trust Theymos' ratings, but not DeaDTerra's ratings", or Theymos couldn't say "I trust DeaDTerra's ratings, except for the Goat one".
I assume adding filtering would be pretty complicated, so I was just suggesting being able to artificially adjust the effective depth, so I could include Theymos but depth -1 him so that it would stop at DeaDTerra and I wouldn't get the irritating warning on my own screen. I could accomplish this purely artificially by creating a "Theymos shim" account, having it trust theymos, and then I trust it.
If ever there was filtering it could potentially do arbitrarily complicated things like only trust someone 4 levels deep if they were reachable by N mutually exclusive paths (e.g. find a path to that person, eliminate all the people along it, and see if they're still reachable).
