After T2674: Allow users to be blocked from editing a specific article or all articles inside a namespace is built, we will want to address page moves/renames into the blocked namespace.
User:Apples is blocked from editing within the Foo: namespaces. Using the Special:MovePage tool,
- They should not be able to move any pages within the namespace
- Foo:Mars to Foo:Mercury
- They should not be able to move any pages out of the namespace
- Foo:Earth to Bar:Earth
- Foo:Pluto to Bar:Saturn
- They should not be able to move any pages into the namespace
- Bar:Venus to Foo:Venus
- Bar:Jupiter to Foo:Uranus
Users will always be able to manually copy+paste a page's content or wikitext — we have no plans to intercept this behavior.
