I don't believe so. I believe it's YouTube's strong moderation tools. Nostr fixes this.
I've had Telegram delete a comment promoting NOSTR, and they put me in Telegram jail for two weeks. Wouldn't let me post in any public chats, just private chats.
That seems odd seeing as I'm in dozens of Nostr oriented telegram groups.
Yes. It does seem odd. It feels like Telegram is slamming the ban hammer harder in some public chats. The owner of the chat says he isn't banning, and has no bots running.
Odd indeed.
