Problem: Wikis are still being inadvertently marked as closed, despite having new pages created as at 15 October 2020, which wouldn't even be inactive. It's, perhaps, possible the deletion script is only counting (Main) namespace contributions as eligible?
Reproducable?: Yes, has occurred on more than wiki.
Relevant link(s): This adoption request on Meta
I do hope we can get to the bottom of whatever this issue is and rectify it, as I definitely want to see wikis automatically as deleted and don't want this ability to be disabled on a prolonged basis
