The collections don’t have rules as you can’t post directly to them. If the collection mod don’t want to have military tech in it, they would have to remove tech from the list of aggregated communities.

This could be mitigated by sorting the posts by votes and activity relative to the community-size.

Kbin had this once. If I remember right, it was called Collections. The Mod of a collection could add communities to it and their content would show up in one list.
