There exists multiple types of people who upload pirated stuff. One of these types is the person who, instead of getting a day job, makes a living on selling content that they don’t own. I don’t know what to call that person other than a criminal. And it’s not too far fetched to assume that some people in that scene resort to pretty nasty techniques to obtain content, and that can be way more problematic than sharing torrents.
Well, even if you don’t partake, there are trackers with subscriptions and they have subscribers.
