When all of the moderator badges was removed (Image Moderator, Forum Moderator, Super Moderator), the privileges may have been removed from the players who had it (unknown what happened exactly, until a former SM tells the community). Some of the SMs were made into Administrators, others, demoted. There is truly no known player with the Super Moderator badge currently on ROBLOX (as of June 16, 2016) for this rank has been removed. But, this thread gives a list of people who used to be SMs.
