~To improve this, I've split up these use-cases:

Use-case #1 is the old trust system, but I made the descriptions on the rating types a bit more general and removed the concept of a trust score. The numbers are now "distinct positive raters / distinct neutral raters / distinct negative raters". You should give these ratings for anything which you think would impact someone's willingness to trade with the person, but you should not use trust ratings to attack a person's opinions or otherwise talk about things which would not be relevant to reasonable prospective traders.

Use-cases 2 and 3 will be handled by a new system of flags. You can create a flag using a link on a person's trust page.

A newbie-warning flag is active if there are more people supporting such a flag than opposing it. It shows a banner on topics started by the flagged user for guests and for users with less than 7 days of login time. For all users, a "#" is shown next to their trust scores.

For contractual violations only, a scammer flag can be created. This is the only thing which causes the "Warning: trade with extreme caution" warning to return. It also triggers a banner similar to the newbie-warning banner which is visible to all users. A scammer flag requires 3 more supporting users than opposing users to become active.~
