Mastodon doesn't have a lack of moderation, in fact, it's architecture tends to segregate people out into instances by interest, making it easy to moderate as long as you keep your instance small (most of the really bad stuff will be on a handful of instances that allow it, so you can just block them and only have to deal with the minor problems on your own instance). Mastodon also tends to have one or more moderators per instance, so it probably has a lot more people with moderation privileges than a big centralized company, which can only afford to hire so many people in the call center to handle moderation.

The key here is mastodon isn't a business, so moderation isn't entirely focused on being cheap. Mastodon, correctly in my opinion, identifies social networks as community resources not as entities to extraft profit from.
