Re-reading the comments, I come to the conclusion that the issue goes beyond a single player. Multiple accounts, cross-faction farming protection, a history of bans — this is an organized scheme, not an isolated case. The fact that this thread is generating a notable number of defenders speaks for itself.
As for the "just improve your PvP skills" argument — this isn't about ability. It's about one group systematically monopolizing a farming zone across both factions for financial gain, which affects every player on the server and trust in fair play overall.
I have already encountered a similar situation around Aether farming. Almost a year passed before I saw the names of those involved in the ban list. I hope the process of cleaning the server from schemers won't slow down.
