I feel like the positive comments are more meaningful because they aren't the only comments I let onto the site. Anyone can voice their thoughts, and it's very cool that most of those thoughts are positive, curious, engaging with the story and picking up most of what I'm putting down. It tells me that I'm doing a decent job at narratively and visually portraying the important parts, but I'm also reaching an audience that won't just automatically approve of whatever I do regardless of quality.
If someone wants to spend an excess of time being negative about me or my work, that really only affects me if I actively seek it out. Otherwise they're just burning daylight engaging with something they clearly don't enjoy, and the only person that hurts is them. Seeking it out to censor it would be self-defeating and a smidge dishonest.
Plus, if I saw a negative comment in the moderation queue, it stung me, and I elected to hide it as spam, nobody else would get to respond with their own takes. It would just be me alone with the bad vibe bouncing around in my head. If the comment goes onto the site, it gets confronted with counter-arguments. It's not just me alone with it, hiding it out of shame that it somehow reflects poorly on me. It's in the cold light of day where everyone can volunteer their thoughts on it.
Anyway, micromanaging a comment section is a recipe for madness. I wouldn't recommend it!
