When you talk about the possible abuse of the trust system by JollyGood then you have to understand why JollyGood tag them with a neutral tag even though it is possible for him to give all those accounts red tag.

But you're not referring to abuse but rather to compare the quality of posts between users who you think don't deserve to be called spammers and are tagged. I've seen actmyname have a lot of neutral tags for the same reason, so why do you just think JollyGood does it and leaves you so paranoid about getting hurt in the future?

I know that belief systems are not for dealing with spammers, but neutral tags are great for forcing spammers a bit to change the interest of their posts to higher quality. Every user you mention in the thread has the right to ask JollyGood to remove or consider the tag, so I don't think it will make you feel intimidated to speak up and post anywhere.
