Consequently red (or any) trust ratings are not moderated either. And yes, some users will post red trust for stupid reasons. Technically they should not be included in trust lists of other users therefore rendering their sent ratings appear under "untrusted" feedback but the system is not perfect.
No the system is not perfect. At least you recognize the problem. Now when you realize that you are one of the people who are largely responsible for this problem with your behavior in a few more years, you can have some sort of awakening and change the type of behavior you support. Chances are you'll be completely irrelevant by then and most of the people you were harassing with your behavior will have moved on to enjoy their lives doing other things so it won't be as beneficial as it could be if you were to have this awakening now, but they say that all people come to the same conclusion eventually. The test of intelligence is how long it takes them to get there. I look forward to seeing how long it takes you.
