anarcanudos on Nostr: When the user changes relays in nostr, should I publish the update of the relay list ...

When the user changes relays in nostr, should I publish the update of the relay list on the old relay so as not to cause problems in case someone finds the old event on a relay that is no longer used? #asknostr #dev

quoting note1nf6…crhk

#asknostr #dev
Morning ya, #gm

To compose nostr timeline for user, should I read from:

a) user configured relays;
b) relay tag in follow list event;

Use only A? only B? Both?

To save a reaction in a note, should I save reaction in:

a) user configured write relays;
b) author configured read relay;

Only A? only B? Both? None?

There are docs in some place where I can read about which relay list is best to load/write event in each kind of situation?
