If there is no algo though then how do the servers/relays "know what you want to see and send it to you" - I knew the rest of this information about public zaps, notes, and relays seeing this info, however, does this also apply to searches, profile views, and chats or communities you enter but don't join ? And how safe are the default relays for Amethyst/Primal ? And what are some good trusted relays public and paid/private ? And lastly what if you are forcing Tor while using a VPN on Amethyst since I believe this is the only android client that allows this at the moment ?
