It's not illegal to download, host, link to or even create a crack, serial to anything or for anything. It's just illegal to use it(and its not like anybody can tell whether u used it for legitimate reasons or not). If anybody was actively shutting down that type of crap then seems like the crack sites I've been usin for the last 12 years would of got shut down by now like all the old "warez" sites ;P

Nobody cares about cracks cause once they're out theres not a thing to do about them. In fact they're software saviors to many people:

Say you purchased some legit shareware but oh no your HD crashed and you lost everything. You re-download your favorite app but you don't got your old serial # anymore cause it was so long ago you lost it,etc so instead of shelling out another $30 for something you already had you go and get a crack. Now you have used a crack LEGALLY. That is why anybody can download em, link to em, make em, do whatever the hell they want with them.

They ain't illegal to host or have and to say they are is purely based on ignorance.
