Diluting the DT list (=adding more DT users) would reduce that PITA.
You keep saying that and you even "applied" to DT yourself but in the last year or so you posted around a dozen trust ratings, 2 (perhaps 2.5) of which are retaliatory and others have no reference links. That's a horrible contribution to the trust system and you should not be anywhere near DT nor have any say in how it should be changed.
If I was Satoshi, would you then listen to these ideas I present?
Look at the first post of this thread. See what makes this DT list and what the DT users do.
DT should not be a group that requires whatever active spam/scambusting you're looking for.
We listen to your ideas now. However, you could be the Queen of Sheba and wed still say they were misguided.
