Until now...
Should never leave negative feedback for personal reasons, esp if you are on the default trust list.
I got drunk one night and left negative feedback for someone based on a personal reason. The next day the community ripped me a new one before I apologized and removed it. I have no idea why the same thing is not happening here.
I'm also on default trust, but I don't personally reserve feedback for business transactions. You were made aware of this yesterday lol
That being said, I don't hand out feedback frivolously. I don't believe TECSHARE does, either.
The trust system is just a way to publicly announce who you personally trust or distrust and why. I'm sure TECSHARE is well aware that if he were to frivolously provide negative feedback to a whole bunch of people it would kill his reputation. Accordingly, I perceive this as an anamoly.
I agree that if feedback is given for invalid reasons (as per what members of the community think) then a person's "real" level of trust and reputation will be tarnished. It is also noteworthy that any given person is only on default trust for as long as others on "level one" of default trust deem necessary for them to be on default trust (in other words this status can be revoked at any time)
