You know that modpack perms and the right to only have the download on your approved sites are two different things right? Obviously you feel strongly about stealing downloads (You headed up the stop stealing mods campaign right?
), as I do as well, but perms and illegal download sites are two completely different things. Also a license wont really stop the baddies from taking the mod. They don't need a license to download the mod, and that is all they need. Only the white-hats ask for permission... XD That sounds like a movie plot.
