I have a fediverse question:

Assume I am a member of instance X that has a rule "never mention Apples", and I follow someone from instance Y that has no such rule.

If I reply to someone from Y with some apple talk, who gets to see my response? Am I breaking X's rules or is it only people on Y and my followers who see it?

Following people from different instances each with different rules makes it hard to know what etiquette to adopt.

I should clarify. I am not referring to obvious bad behaviour rules (racism, homophobia etc.). But more subtle ones, for example, here on vis.social, not showing AI generated images, that could legitimately vary between instances.

Ideally, when I see posts in my timeline, I'd like not to worry too much about checking the instance of the poster in order to know how best to reply.

I think perhaps my mental model of how people's timelines are fed is wrong.
