Lmao this won't do shit, at best he'll get a mega taken down and then there'll be a new one within an hour, these aren't huge projects by dedicated teams, they're just text that's perfectly legal to write and damn near impossible to stop people sharing.
He would just be wasting his own time trying to legally fight mods, people have already figured out how to make them and a few are being worked on atm anyway, including a Kinu one that redoes her massively.
Hell there's been a mod out for a while now, though I think it mainly removes some of the dumber content currently? There's also a Quin anal scene and some other mechanical stuff like higher level cap and drinks, but I don't believe any of the larger mods are done yet.
