The only people who defend and say it is not plagiarizing are people he includes on his trust list/has left positive trust to/regularly showers with merits. Everyone objective says it is plagiarizing. Still don't know why mods don't ban.

Retaliatory feedback is wrong, doesn't matter if feedback you have been left is correct or not. Calling people names in feedback with no reference is worse. Death threats in feedback is against rules and he should be banned.

Negative trust for plagiarizing is different topic, but if you are happy to steal intellectual property then you are also happy to steal physical property.
