I kinda do this but with a core profile for system functions that can't be done in other profiles, then separate profiles for pretty much every category of stuff I might do - gaming, using nostr, using my google account, etc

Can be a bit cumbersome if like, I see a meme on nostr and want to share it on discord, but cybersecurity sucks these days so there's not much else to do about it 

 You could have simplex chat which has a group chat with all your profiles. Group chat with self destructing messages every 24 hours
