I was curious about how much upload you need to possibly become a privileged user, then I took a look at https://e621.net/users?commit=Search&page=2&search%5Blevel%5D=30&search%5Border%5D=post_upload_count the user list, surprisingly some of them do not have many posts/notes/edits which I was assuming will be at least 200+ before I look at it.
So, what makes them become a privileged user, or is there another way to become one other than listed in the wiki? (https://e621.net/wiki_pages/2423)
And a sub-question, how to know whether the upload is with premission?
