Bluesky is a perfect example of privacy through obscurity.

It's private until one or two CHUDS get accounts and pass the invites to other CHUDS and the next thing you know your gangstalkers have accounts.

And even better, if your gangstalker is blocked, he can just make a new alt account with an invite code if he's dedicated enough (never underestimate the power of weaponzied autism).

Basically Bluesky users forget the first rule of opsec, if you say anything online someone will fucking read it (if you don't have to say it, don't!)
