If the descentralization of social networks continue, we will have to prepare for the eventual rise of the instances wars, where people will start to fight about which instance is better and which one is weird to be in and so on, but that’s for the future of us all.
I’d guess it’s a mix of your post and the parent post. Lemmy instances will have a user verification policy and de-federate with instances that differ too much. So the Lemmy instances with emai verification and 2FA will eventually de-federate from an instance that wants to be anonymous and has zero requirements for creating an account.
Maybe curse me for bringing the idea up, could a Lemmy instance exclusively use Facebook’s login features? So that you have to use “login with Facebook account” to create a Lemmy user on the instance?
Oh god.
I don’t think the Lemmy code base supports that yet, but adding OAuth support is a natural thing to do at some point. I guess if you were dedicated you could hack it together yourself in your own instance even now.
As horrible as it is the implementation would take Facebook only a few days since lemmy is open source. The “problem” with an open system ist that basically everybody can join
Facebook will definitely hide behind a Facebook logins defederate everything that they don’t like to “protect” their users.
