@Nox Search is instance based. Every admin can choose to implement it or not and each account has options to limit their discoverability by search.
So those who don't want to be found have MANY options to limit their visibility. Whether that be by locking their account, posting with "unlisted" visibility, posting with "followers only" visibility, or turning off search discovery features.
There's no reason to harass devs of discoverability services because each person can protect themselves.
Since search is instance based, I have to go to mastodon.social to search for content i'm interested in because they're the most federated instance. It's just an annoyance.
