Everybody says so, but so far I didn't see any realistic proof, other, that it's "russian guy" behind. There is of course some concerns, lot of spam and frauds (well, when Nostr hit's majority user, guess what happens here), but I can hardly find so well supported and community used alternative. It is what it is.
