What allows you to have a set with over 10,000 posts, aside from being privileged? Cuz i seen people with 0ver 10,000 posts on their sets that don't seem to have anything special about their profile

As far as I know any set with over 10,000 posts comes from many years ago, before the limit was put in place. Even privileged users now have the 10k limit.
