Is your proposal related to a problem?

Even if a local user's report of a remote community is resolved by a remote admin, a local admin might still have a problem with the remote community.

Describe the solution you'd like.

• List reports of remote communities somewhere for local admins. I'm not sure if it should be a new separate list.
• Add a filter to only show reports that still need review by local admins. It will at least hide reports that a local admin marked as resolved. Maybe it should also hide a report if the community is already removed.

Describe alternatives you've considered.

This could be implemented with a separate column resolved_locally.

This applies to comments and posts also I believe. If a post / comment is resolved on its home community instance, that resolve gets sent out to all the federated community moderators and the targets home instance.
