As far as I can tell, it's not a grey area at all - it's illegal. These cracks always seem to either be modified versions of a copyright exe, in which case it's a copyright infringement, or they're some kind of bye patcher, in which case you're modifying a copyright-protected original exe.
It might be a very grey
moral area, in that I and no doubt millions of others can't see anything
wrong in doing this so that you can play a game you paid for, or even just legitimately own even if you didn't pay for it (like received it as a gift) though it's very different if you do it for a pirated game. But that doesn't mean it's not illegal.
Which makes it a grey area as far as we are concerned. While we sympathise with people doing it for legit purposes, it puts HEXUS on tender ground.
So please, no discussing of where to get, or how to apply such patches, or of recommending them, or discussing version merits and so forth. They aren't hard to find and anyone able to find HEXUS ought to be able to find these, so we don't need to
There's no problem (that I can see) with discussing the rights and wrongs, or opinions on such, but no promoting of them, and
no requests for PMs with info either.
We're on thin ice here. Please don't put any "cracks" in it.
