I was thinking, since this is a place for discussion, what is the policy on submitting your own work (not that I have any)? Does certain self-generated content have more value than others? If a user posts a song they created and asked users to check out their album, would/should it be removed? What if the user post a link to their own paper and asked for reviews?
Maybe this is an issue that has to be handled on a case by case basis, but if the community increases in number, it would be increasingly difficult to monitor.
