I still question the extent to which DT actually adds value to the forum, rather than contributing to some kind of semi-quasi-irrelevant popularity contest... which might even unwittingly contribute to the enabling of long cons, in certain circumstances.
Indeed, I maintain that trust should be awarded exclusively based on trades or other kinds of financial transactions (escrow etc). Otherwise, it really becomes a sort of popularity contest, with con artists that one fine day choose to perform a sort of exit scam.
This might happen even with properly trade-based trust of course, but with much lower likelihood IMO.
