I've been doing some tag cleanup work, and I found a couple cases where there was a very old migrated question placeholder still alive. It turns out this is because the question was deleted from the target site before the 30 day limit on the placeholder was up.
This is a problem because these orphaned questions are difficult for the community to moderate. At first I couldn't even find a way to flag them for diamond mods to fix. Fortunately, there's a low incidence of them, but I still feel like it's a bug.
Instead, we need one of two behaviors:
- The placeholder is removed from the original site
- The placeholder is restored as a normal question on the original site, but in a deleted state.
