That would be a problem if it wasn't trivially easy to block them. Otherwise, people being horrible really isn't your problem unless you train yourself to be very conscious of their opinions and to care deeply about them. That's the only way their opinion can get to you. Of course, that training doesn't have to be conscious and a great many people have inadvertently trained themselves to be sensitive to the opinions…
If you get hit by thousands of trolls at once it's not trivial to block them. Also, in some cases other people see the trolling about you even after you block it.
Don't get me wrong, I see why it's a pain in the ass to wind up with a popular comment even if the comments are mostly positive (and especially if they're not not), but I think this is better handled by UI and rate limiting on notifications rather than the alternatives.

Pardon my arrogance, but I don't believe it's your place to determine how other people are allowed to talk about you even if you've excused yourself from the conversation. Down that path lay dragons. For a quick example why, sub out "you" and "your" in the previous sentence for the name of any unpopular politician.
