These days I only bother commenting if I really feel I need to get something off my chest, but I don't assume anyone gives a shit. I frequently just delete my responses. I don't generally feel anyone needs what I'm saying.
It takes a bit of self-awareness to realize that no one is interested in what you have to say, so don't bother. And, I think it takes twice as much self-awareness to realize that they certainly don't care about what a bot has to say, unless they're the ones asking.
