they can't respond to any of your threads
Great, but my posts make up a tiny fraction of the content I consume.
With blocking, there's no PMing
That's the conceivably useful new feature I didn't see anyone clamoring for.
no ability to respond to any of their comments
I missed this. So the troll has to wait for someone else to comment first, then they can comment. Or they can comment parallel to my comment.
I don't care where the troll comments or what they say. I am not interested in trying to control their behavior. My proposal is to make it easier to ignore trolls by concealing their comments.
