What are the best private messengers?
Signal requires a telephone number. DMs in Nostr are encrypted but can’t you see who sends to who?
Or is it whom?…
Replace each who/whom with he or him and ask yourself what seems more correct.
...can't you see he sends to him?
he = who
him = whom
Therefore:
...can't you see who sends to whom?
...can't you see he sends to him?
he = who
him = whom
Therefore:
...can't you see who sends to whom?
