Judging by the number of rage posts Thue recently posted and his seemingly recent inactivity, I am guessing he recently had a temp ban expire.
I am not defending his behavior (I am personally annoyed by his [and others] posting habits), but I really don't know what anyone expects someone like Thue to act when in his situation. Most of his negative trust was received as a result of him defending himself, and he originally received negative trust for doing something that is explicitly allowed per the forum rules. Before anyone bring this up, no scamming is not allowed per the forum rules, the forum does not moderate scams -- there is a big difference; also if you scam someone and this has been proven, the administration may out you when you try to come back under alternate accounts, and this has been done many times.
I don't find it unreasonable that he is trying to defend his reputation. This is what most people initially do when they receive negative trust for arbitrary reasons, but most people usually rage quit, except Thue has decided to continue defending himself. If nothing is going to be done to address his trust situation, and his behavior is unacceptable, then he might as well be permanently banned now because I don't see any reason why the end result will be anything different, and it would save everyone the trouble of having to see his off topic posts. I don't think this is a desirable outcome (quite the opposite actually), this is just the reality of the situation.
I don't think suchmoon should get tagged for buying one of Bruno's accounts. Suchmoon does have a decent amount of trust, a lot of merit, and is on many people's trust lists. If someone was looking from the outside, and saw suchmoon do something, they would reasonably think, based on her stats that it would be acceptable to engage in similar behavior. Suchmoon is not the only person who has bought/sold forum accounts that can be described this way.
Some have argued they don't want to go back "far in time" to tag people who have engaged in this activity. However I would ask those who regularly tag these types of people what they would say if someone saw that a very "senior" (lot of good trust related stats) forum member did something, and assumed this was acceptable behavior, and proceeds to engage in similar behavior?
