Hmm. I can't give great stats but looked at the most recent 100 pages of deletions, and counted 135 occurrences of "Unapproved in three days after returning to moderation queue". Roughly 5.4% of the most recent 2500 deletions. The vast majority are standard mod queue 3 day deletions. Easily over 90%, particularly if you exclude bulk deletions by artist request.
You could add a couple to that 135 that got outright deleted after being flagged without waiting three days, and thus have a different message - I've done this with blatant TOS violations like extreme guro and nude filters. However I don't know how many that would add. Probably not enough to significantly change our conclusions.
Now, the thing is the recent deletions list is not timestamped so I'm not sure how much time 100 pages represent. A quick estimation from status:deleted is that 2500 images were deleted in the last 6.5 weeks, however my understanding is that that search orders by uploaded-date, not deleted-date, thus it's not a 1:1 correlation with the deletion list. Hopefully it works as ballpark, though?
The other missing variable is how many images were unapprove-flagged in the last 6.5 weeks. Without that, I have no idea what percentage of those images are being reapproved.
My own experience is that unapprovals make up a relatively small proportion of the queue. However, these days I tend to moderate the entire queue every two days or so, rather than check it in small visits every few hours. So it could be that the majority of flagged images are being approved before I see them.
I did notice that I saw proportionately less "Unapproved in three days after returning to moderation queue" deletions in the most recent 25 or so pages of the deletion listing. So either less things are being unapproved lately or more of them are being reapproved. Again, I can't be sure.
