I don't think this sort of fedi/Bluesky user would very join nostr.

I don't even think they believe their own 'nazi' accusations. It's more a snarky stick to beat people with who they don't like. (The only potential 'nazi' user on nostr are more like the 4chan spergs posters).

They are quite happy on fedi/bluesky they were never banned off platforms in the same way, they don't need that aspect. They can literally post everything they post on there on twitter. What they wanted was for the 'bad people's to not be able to post. And Nostr doesn't offer that.

I don't think this market is worth pursuing maybe ¯⁠\⁠_⁠(⁠ツ⁠)⁠_⁠/⁠¯
