I removed all my negative ratings from people who posted in that particular thread that you linked to, out of respect for what Lauda and MadZ said. I'm not going to kill the forum by doing so, and there weren't that many negs that I left there.
Regarding that one, I don't like the fact that Omegastarscream was dealing in accounts, but I do take other factors into account before leaving someone a neg for account trading--and one of the main factors is other positive feedback. Who left it and when are also important. OSS had pretty much proven himself to not be a scammer by the time I visited that thread, so I did not think it was appropriate to leave him a neg. The other users didn't have those reinforcing positive feedbacks, so all I had to go by with them is the fact that they were looking to buy/sell an account.
There are going to be inconsistencies, I don't know what to tell you. Point them out to me and eventually I'll correct them or otherwise respond to the accusations.
Maybe I was not clear (or maybe you did not read very closely). There are instances in which you leave trust for behavior that took place a long time previous to the time you left the Red Tag.
Probably a little bit of both.
I don't go back into old threads, looking for account buyers/seller to neg. I think I did that in 2016 but haven't tagged someone for ancient history infractions in a while. I could be wrong and I could have done it by mistake if a thread got bumped and I wasn't looking closely at the date, but I don't actively seek out really old account sellers & buyers to neg them.
