Few things I despise more than an absolute number provided with no context. Is 60K a lot? A little? The usual? How much does it deviate from the norm?
But I'm betting this week was an outlier for some reason or another.
I'd be interested in seeing something about user IDs that scroll some minimum amount vs user IDs that just post.
My account got nuked because I changed my birthday date for jokes and it locked me out for being 'too young' when I signed up way back in 2007. I would have needed to provide photos of government ID to re-activate so I let it go.
I'd expect in general the number of people who leave a site but don't bother to actually go through the steps of deactivating the account to be quite a bit higher than the number that do deactivate.
