Problem is, going that way you end up in censor land, and therefore unappealing and hated.

If you use paid relays, little to no use, it become a tiny Eco chamber.

Leaving it open to everything is the way, using clients that filter the content to hastags you follow and people you follow should suffice. And for those that love to pay for services, paid relays censoring everything they hate to read, their money, their choice , for everyone else, freedom!
