Did Nostr basically killed Sphinx Chat? I tried to connect again and it's a real ghost town.

Too bad because there is good ideas like the option to pay per message in a group chat and to stake sats to write in order to avoid spam (first time you write it blocks a certain amount in sats, and if you are not reported as spam x hours after your last message, you get your sats back.

The way to agree on what is spam or not was still to improve (only the group admin could judge) but the seed for a solution was planted.
