- local humans : add a custom question in the sign-up/registration form to ask them something about their neighbourhood or just to vouch that they are part of this neighbourhood. The answer can be public or not, make sure you set up the right permissions, here is a guide ; For real human, I will put the answer in point 5.
- was answered in this thread but you have to learn to play a bit yourself with groups, permissions, and categories

- I’m still figuring it out, microsoft share point/teams/azure us a similar feature
- For real humans : Either restrict sign up allowed email domains to famous domain like gmail that require already a phone verification, search in admin for allowed_email_domains; or enforce 2 factor auth, search in admin for Enforce second factor, the only drawback with the 2 factor auth enforcement is that users must use it everytime they connect and this could be bothersome. I wish there was a setting to require it on setup only and then ask it every x time but there is not. Good luck with your projects !
