Or rather, this is the amount of distinct pubkeys that has been posting at least one event since that tweet. I tried to delete the event but it’s impossible 😅

its deleted for me ;) 
I tried to delete it from all the relays I’m connected to but it kept showing up on Damus and Astral
*shrugs*
you can do a fetch from relays directly for that event id to confirm.. if you want to.
Seems like it’s wss://nostr-relay.untethr.me that is not respecting the deletion event. It’s software does not yet support this NIP: https://github.com/atdixon/me.untethr.nostr-relay
ok, good to know.. !
I was seeing some weird deletion results yesterday when pinging the relays from python (specifically the Damus and Zebedee relays). The deletion requests were published but I was still receiving the events. It wasn’t clear to me from the spec whether it’s the client responsibility to hide the note or whether I should have stopped getting it via requests as well
#[2] is there actually a behavior difference of what you receive if you request a specific event ID vs the last 10 kind 1s of an author? I have noticed from some relays I will actually get the delete request back instead of the event if I request directly by ID
