My feedback mentions nothing about trading.
It's in the forum's explanation for Negative feedback:
After clicking it, you're on the user's
Trust summary. Read the description per Type carefully:

Note that the description for Positive, Neutral and Negative is different than it was 4 months ago: it was changed when Trust Flags were introduced.
That's nice.... again, my feedback has nothing to do with trading. If this is the only reason a person would leave a negative, then 99% of negative trust should be deleted.
