Yes, modders can also trigger the anticheat on a victim's machine, causing the victim to be banned.

Rockstar Support sees the ban as legitimate but they seemingly do not comprehend that things can be triggered on behalf of other clients.

I got banned in July 2022 because a modder did this by causing a bunch of collectable unlocks. I am still fighting them to this day but it is moot. Almost a decade of time spent with this game down the drain.

I even tried mailing multiple letters to their New York office. Nope.
