Yes, the status is broken. The tool is working but not unsubscribing.
The source of the problem is that I cannot access the count of local subscribers at the moment. Therefore, it is not clear whether the tool should unsubscribe or not. I’ve created a merge request for this and the problem will be fixed in 0.19.4.
It looks like reddthat.com is on 0.19.4 and it’s working correctly for them now.
