Concerned with your spectatorship! (9)
I believe the answer is:
regarding
'concerned with' is the definition.
(I've seen this before)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for regarding that I've seen before include "Concerned with" , "Seeing" , "Gazing" , "With respect to" , "Considering" .)
