I'm right there with you. The whole legitimate use thing is a thinly veiled attempt to seem like they're legit. The vast majority of its users are there for the piracy and anyone who tries to say that the main purpose of the site was for anything other than that is either just lying to themselves or just lying. The fact that it can be used legitimately doesn't mean it is nor does it mean it was ever intended to. This is just a really weak case of plausible deniability
