Well, he's an idiot then, because if somebody cares enough they WILL crack his mods again. I doubt anybody cares though. Frankly I just switched over to VAM after discord got nuked, much easier to port things and a much more active community.
Don't quote me on that, but I am PRETTY sure they literally can't do anything to you if you spread the mods, although I imagine if you live in USA you'd have to deal with idiotic court system IF the modder who made the mods is filthy rich and wants to spend his own money and time to bother you.
Modding Illusion games is incredibly annoying and time-consuming ( I know because I tried porting an outfit once and it took me 5 full evening just to be done with weighting, porting heads looks like it'll take at least two weeks IF you're experienced) , which is why I don't mind when modders prefer to make some money out of it, especially if it's fairly priced.
You'd have better luck switching to VAM and porting heads there, since it's MUCH faster and less obscure, at least judging by the rate people pump out head mods there that are high quality.
