Everyone is anon including the OP on the other apps mentioned, so you can’t just target people you don’t like and make anon reply guy comments on their notes.
I see the difference, but who is going to see the anon notes if everyone is using UTXOs web of trust? Anonymous notes are difficult for plebs to discover.
I don’t think many people are using those relays. I don’t. You’ll miss a lot of great content by using only WoT relays.
Anonostr is closer to a full client, but with disposable npubs. I've integrated heavy anti-spam measures. But agreed that WoT makes it somewhat irrelevant. Although, I hope Anonostr can be used for whistleblowing or folks who don't care about a follower count.
