I believe there's other AAA PC games on the market that have multiplayer and a better anti-cheat system then what R* could ever come up with in a million Have you tried contacting Rockstar support if this definitely can stick to your character? I'd be curious what they have to say about this but knowing R* and how incompetently they handle things they'll say you did something to trigger it and your in there for good now and close the ticket.
It's the victim who get's punished in the end No, if you thought that then the Anti-cheat system would be working as intended. And guess who the system punishes more in the end? The villain(s)? You had one job to do on the PC Platform and that was to design an anti-cheat system where anyone who comes online with modified files or trainers get's auto-banned but even you couldn't get that right.
