I don't think this is the best way to use your custom Trust list. "You should exclude users who leave inaccurate feedback." [reference] , but I guess that's your prerogative and you can do whatever you want with your trust list as far as I'm concerned. Although I'm not entirely sure what I did to step on your toes, I don't really care.
FatFork, I support your neutral tag, thanks for bringing this to your attention. In this case, this is a clear abuse of the merit system, and in 2018, red tags were left for such cases immediately, so the neutral tag, written without any insults, it really is the place to be. But arguing with those who have double standards in the use of trust system, in my opinion, is pointless.
I am surprised how this issue lingered. Though the issue is somewhat controversial and any decision taken by anyone here would be considered as fair if it does not leave a neg tag.
The above case has some signs of;
1. Merit abuse
2. Alt connection
3. And a poorly scripted drama by dumb actors.
If the victim was to help a friend, would it not be better not to send the merits at once considering the quality of the post upon which the merits were bestowed.
If someone could leave a neutral tag to a user which he suspects and eventually changed email. What's the big deal leaving a neutral tag on a suspected merit abuse post.
