I would support a list that filters out bounty spammers.
However, I would strongly be against a list that ignores all newbies/junior members/users who have earned 0 merit.
So, you would use the code from a bounty spammers list. And you would not use the code list that ignores newbies users.
I think the same of the trust setting, though DT is the same as your idea in a way. People don't understand it enough as is, and I think having an option like this would only compound it.
It would not be the same. A specific purpose list is different from a personal opinion you have about someone. In the current system, a member of the DT2 group can send trust for any reason. He may have traded something with the user, He may believe that the account has been sold, he can trust the user by being a well known person, or he can give a negative trust by knowing that he applied a scam in the past or promoted an MLM .
We recently had a case where a user has received a negative trust because he has the nickname #bitcoinCore.
I think these lists would be very useful for the local sections. For example, I believe that there is no member DT1, DT2 or DT3 that frequents the Portuguese section. So instead of requiring that a DT2 member send a negative or positive trust to someone who wants to do business exclusively in that section, we could have a list that is well accepted and trusted locally.
With the current system, most would have to include some known user on the trusted list. But no one ever did.
I found it quite interesting that you will offer a system for appeals on your personal list. Apart from the big lists of the forum like SMas, it is very unlikely that a user can know that he is on the list ignore someone. Unless it is communicated.
