It's /speclist
/speclist is something different than /spechide,
speclist shows whos spectating you, or whos on the spectate list, as for spechide it makes you invisible on the speclist of other players, so that no one can notice that ur speccing him.
on the other hand /spechide was made to be mostly used by admins i dont see any reason why normal players should be able to use it ,
