Generally we can post topics and comments in any instance and can be viewed from any instance.
After defederating, the communication between the instances will be cut. so we cannot comment/post with the instance that was defederated.
To add on to this: Instance admins have no control over moderating content from other instances that they’re federated with. An acceptable post on one instance could be rule breaking to another. The only option that other instance has is to defederate. Admins have acknowledged defederation is an extreme measure for what is often just a few problem communities or users, but they have no other option.

Is there not an option for blocking just that problem community or user?
