I have already replied about the 1 account trade I had (it was done in the open as are all of my trades). If anyone would like to drop me a negative by all means go for it. I have never dropped a negative for retaliation or due to trash talking me. I only negative if someone really earns it. Back in 2013/2014 account sales were not deemed bad/shady since the spam issue was non existent compared to today. For the record I was only DT2 back then not DT1.
You could remove those in your trust list who have participated in the Red Tagging of sold accounts I mentioned in the OP, who as of now, have failed to Red Tag you:

Removing the above users would remove any
real or perceived conflict of interest within your trust list.
This would not preclude others on DT1 from adding any of the above onto their own trust list, if they believe they should be in DT2.
You can publicly state anyone is free to drop you a negative all you want, however as long as these people remain on your trust list, it will appear you are being protected.
