But people here don’t really care that much about celebrities being here and maybe not even their username being unique. Could probably be anon1, anon2, etc and it wouldn’t matter that much, since real identity is probably not a draw for them. Focus on regular people wanting the userbase to want to use fediverse rather than celebrities which is an off-putting first impression and point of sale for lot of people here.

You need to pivot is what I’m saying to achieve what you want.

I’m not here for celebrities and they will always flock to centralized platforms anyways, since they are all about the views.

Not really. These aren’t monetized sites, but just individuals inviting guests to use their instance over self hosting their own, and there’s other instances people can move to.

Each instance is better seen as individual forums than a reddit type centralized site. Some forums allows cross account logins, and some you have to create another account. And defederation doesn’t cause that instance to cease to exist like banning a community or subreddit does.
