Nice to see people are using it like this :-)
A caveat to "The Uganda Communications Commission has warned that the government can disable Bitchat. I wish them luck. It's technically impossible to remotely shut down Bluetooth on individual phones without confiscating every device." You can (and governments can too) jam signals. Hobby equipment can jam tens of meters, professional equipment several hundred meters. Anyway, that also seems like a significant challenge for a government to achieve.
