"Bay-bee shark doo-doo, doo-doo doo-doo..."

Sarcasm aside though, I think you might have fallen into the habit of using your disinterest performatively to try and discourage the kind of noise you're talking about. I get it, I do, but calling people out that you're intending to block either hurts the people who've made one dick comment or encourages the kind of people who make said dicks comments because it amuses them. The people you don't like aren't going to start respecting your opinion or regarding your actions as understandably reasoned just because you point out what you're doing.

The third option is that you're doing it to be smug? But from a brief scroll through your comment history that seems really unlikely. So, given the absolute hell the world is devolving into, does this really do anything positive for you? Because to an outside observer, this seems like the non-cathartic type of void screaming. I'm truly sympathetic there, and it might be worth it for your own peace of mind to start blocking more frequently but just moving on from there. Giving attention to people you write off as without value cannot be personally constructive.
