The system does not automatically clean up rejected migrations (questions sent here from another site, then closed here as anything except a duplicate).
Since rejected migrations are locked by Community♦, there's not much non-moderators can do about this (e.g. vote to delete) except flag.
I was thinking about going through these and deleting rejected migrations where:
- The question is locked and closed (not as a duplicate)
- It was last active more than 6 months ago
- There are zero answers
- The question is not a migration away from dba.se (the system handles these)
The search query I am using is:
is:question closed:yes duplicate:no locked:yes answers:0 migrated:0 lastactive:...6m
This finds 148 questions at the time of writing. I review each one carefully before deleting. Can anyone think of any reason not to do this? Any other input?
