From the Workplace Meta-FAQ post about community delete votes:
Generally we only delete closed, low scoring posts with no answers or
poor answers. Closed posts are all "candidates for deletion" but
generally only irrecoverably off topic/poor questions without useful
information in answers should be deleted.
The two day waiting limit is imposed on 2,000 rep users so there's a
window where the asker can edit and improve their question, or at
least see why their post was closed. Even if you have 4,000 rep,
consider waiting until the user sees what was wrong with the question.
That is the standard I try to follow on all SE sites.
- Closed
- Low scoring
- No answers, or nothing but poor answers
- Irrecoverably off topic/poor question
- No useful information in answers
- Not recently active (at least >2 days since last activity), and no one is activly working to try to edit/reopen the post
If I come across a case where something doesn't match that list but I still think it should be deleted for some reason, I would discuss with the community and/or our human exception handlers (the moderators) first.
When voting to delete, I am voting to take content away from the entire community, and I take that responsibility very seriously and try not to let my personal opinion of a post affect my decision.
