Group reportedly censored (4)
I believe the answer is:
band
'group' is the definition.
(band is a kind of group)
'reportedly censored' is the wordplay.
'reportedly' indicates a 'sounds like' (homophone) clue.
'censored' becomes 'banned' ('ban' can be a synonym of 'censor').
'banned' is a homophone of 'BAND'.
(Other definitions for band that I've seen before include "Group; frequency range" , "Music ensemble" , "A collection of musicians in ring" , "troop" , "Pop group; stripe" .)
