Agreed to this comment above me
While I do play Roblox (because we don’t have a federated alternative for it yet) I had concerns about it - moderation, playerbase maturity issues (yes, while its being taken over by young adults the majority is still unmatured), updates that the community doesn’t want, and “racism” against other platforms e.g. Linux. You’re right about how they exploit the creators.
Like this rejected Minetest suggestion
