Mastodon doesn't necessarily have less moderation, it just has a different set of knobs to tweak to accomplish the act of moderation. The decentralized/federated architecture makes it simple for admins of instances to ban whichever other instances they see fit. In practice, this means that it's effectively easier to ban unsavory users of certain undesirable types, since they tend to congregate on the same instances. On top of that, there are traditional ban controls at both the user and admin level. I've been a Mastodon user since 2017 and I've found it pretty good with respect to moderation and unwanted content. Maybe I've just gotten lucky with the instances I've chosen, though.
