In my opinion changing ratings for inactive accounts is a rabbit hole we do not want to go down and will inevitably create more avenues for manipulation and abuse. I think that if a user is trusted, they should appeal to other users to leave them positive ratings to counteract the negative rating, specifically noting the situation at hand with a referenced thread. This should rectify the situation to a large degree.
Unfortunately, the way that the trust score is tabulated, it is not fair to SwingFirst. He has 3 positive comments, followed by Zepher's negative, followed by Jet Cash's and my counter trust. SwingFast's current score is 1 when it should be 30. This is an exception case; however, since we know Zepher is dead and Zepher made it clear what his intentions were in a post when he left the negative rating.
What makes it worse is that each unique positive rating that SwingFirst receives from now on will only add 1 point to his trust score instead of slowly counting up to 10 points toward his trust score.
Not fair according to who? Why is it the entire community now has to suffer a potential exploit because this individual user did not secure their account correctly? Yes it sucks, but if there are not standards then it is a continual never ending slow creep toward abuse. SwingFast made a mistake, they should bear the responsibility for it, not pass it on to the community as a whole.
