As per that logic, I should have been in many people's trust list by now. But, fortunately or unfortunately, I am not.

Tell me why?
You haven't sent a lot of feedbacks and also you haven't been noticed by a lot of people. I can't remember if I have seen this username before this time. Also, it doesn't guarantee that you will be included when you sent a lot of feedback. Your sent feedback accuracy should be good and helpful for others when they trade. It's all about actively participating in the trust system and also in the forum discussion (to get noticed by others).
