I was a mod on a couple of subreddits that have more than a million subscribers. It's a thankless task. Most mods I've interacted with are absolutely fantastic, spending their free time volunteering for the community and genuinely making the community better. Filtering out spam, harassment is a daily, endless task. The only time people talk about the moderators is when something goes wrong.

The main reason I stopped doing it is because it was just too much work and having the community mainly shit on you doesn't make it more enticing to continue. Everyone assumes the worst about you, how you're somehow in it for the wrong reasons, when for 99% of mods I've interacted with that definitely wasn't the case.
