🤔 how does it work when/if I would want to participate in a community on your instance?
Post to it, comment on things...
Philosophically, I'm thinking about 'owning' a forum vs 'participating' - how to not have federation become fragmentation.
For me, it is perfectly OK to have different rules for local and federated accounts in a community, but maybe some communities will want to organize this in a consensus that goes beyond the 'owning' instance.
(Maybe I'm also - still - misunderstanding how multiple instances and federation works. This is also an invitation to think about these things / make them clearer (to me, and in general)).
The community is at a different level than instances or federation. For example, the rules a community agrees on aren't typically related to your instance or handled by the instance moderation team / admin.
Every instance will have some kind of terms of use that you must follow to keep an account on that instance.
A local community specifically for the bureaucracy of the local instance is also a special case.
In general, posting / replying in communities should be encouraged no matter which instance the community or your account was created on.
However, if you are breaking either your instance's rules or causing problems for users on another instance you can expect to be reported and likely have some moderation actions taken against your account. Basically, just having an external account isn't a license to behave badly.
