gm the censorship resistant social media nostr requires fully tunneled vpn to access from china because most of relays and clients are blocked by GFW.
and you're compromising your whole terminal's internet connection especially for the china based services.
so practically there's no way a user in china could frequently use nostr like they could access Twitter via eg, partially Sockes5 proxy, if they don't build their own relay and aggregation server.
ironically, standard vpns like Nordvpn is totally not accessible because they don't use any obfuscation for their WG alike tunnel and it's easily blocked.
Mullvad is great and accessible even tho the GFW is clearly easier to block its traffic.
