No, the host instance will not proliferate your input to other instances. Only your instance will have that and will only share it with other users from your instance.
e.g. I’m on Lemmy.world. I post on the Beehaw gaming community. Only other users from Lemmy.world will see my posts.
Federation can be a one way street. The problem with that is your comments and votes will only be visible from the instance you did it from. Lemmy.world will show other Lemmy.world users your comment but Beehaw will not ever see it, which means your comment will not proliferate to other instances either.
You can still browse content from an instance that has defederated yours but your actions will only be visible on your own instance.

Live bamboo will create a small pressure bomb.
