You would never want to use a big platform that had no moderation, the quality would be shit. For a small, niche platform, it's fine, but as platforms grow they get filled with 13 year-olds posting garbage, which someone has to clean up to avoid driving away other users.

Become a mod on a reasonably sized forum and see for yourself.
