I've blocked them, but I wish they'd stop entirely. The reason I blocked them was not even because I disagree with copying content (I'm fine with that in some cases), but because it was just spamming posts that nobody wanted to engage in. It was post after post with zero comments.

Side note: hot sorting sucks and need to be improved. Why the heck does it like to show so many brand new posts with not even a single other person voting on? If I wanted to see new posts, I'd browse new. I expect hot to show me things that at least a couple of people have said "yeah, this is good" to, first (and ideally more than just a couple).
