the weird thing about bitchat is.. well.. it creates new keys, so .. unless you want to get harrassed off the platform, probably gonna need (all the stuff we try to do to prevent spam and harrassment, like lightning payments, wot, etc.)
or provide some relays that are tightly integraged somehow with bitchat, using bluetooth proofs of location or something.
anyways..
if not it will probably get ruined just like free relays did.
