I think many people just couldn’t care less about pirating and believe the companies can’t figure out who they are. For example, I discuss pirating stuff pretty openly on my reddit account. But every single comment I make, I consciously make sure to not reveal enough for people to dox me.
I also don’t have Facebook which is how most people figure out identities.
“Hmm, they’re an underwater welder from a specific small town and they have three sons. Well this is the only Facebook profile that matches that so I bet it’s this person” type of thing.
