Anybody on top of fake jacks? Noobs will not know that the name is nothing in nostr.
Discussion
How can they be handled?
So far it would happen very publicly if somebody went to DM users with a fake jack account but still, who would do something about it? Teach people to not trust names I guess.
add the last 8 of the string ( jack 1234 5678) to the name, like a PGP key ID
Fakes will quickly become an issue. Everyone, especially influencers, coming over from Twitter should be encouraged to post to https://www.nostr.directory and check the directory before following ppl.
