@fiatjaf I think njump relay need to both implement and respect NIP-70 and NIP-62. Since it collects data over the network, people need to opt out for it. For their whole pubkey or just one event. I know people who tried to delete their notes from njump, they even asked me and I sent direct nak requests for them but they still find their event on njump. This is really really important. I know all these stuff can be gamed by bad actors collecting everything and do nothing about it, but we need to respect this as much as possible specifically in clients like njump where people try to find something first.
