I think people should leave negative trust only to users who scammed or when they strongly believe that person would scam if given the chance.
The inclusion of "strongly believe" gives enough room in my opinion. We should not leave negative trust if we don't honestly believe a person has scammed or will scam.
So I don't think the description should be changed to "You distrust this person" or similar.
So should the "Positive Trust" description be changed then and the "You trust this person" part be removed? I find it somewhat confusing that on the one hand, people are saying "Negative Trust ratings should only be used for scammers"... yet seem happy enough for the positive trust description to include a very generic "
You trust this person or had a successful trade" description.
So, Positive Trust for someone you simply consider trustworthy = OK... but Negative Trust for someone you consider untrustworthy = not OK?

I guess, the point I'm trying to make is that the descriptions for positive and negative trust are not consistent... hence, I am not surprised at the lack of consistency in how they are interpreted and applied.
