Fans weren't hiding their response (6)
I believe the answer is:
answer
'response' is the definition.
(I know that answer is a type of response)
'fans weren't hiding' is the wordplay.
'hiding' indicates the answer is hidden within the clue.
'ANSWER' is hidden within 'fans werent'.
'their' is the link.
(Other definitions for answer that I've seen before include "Acknowledge" , "Write back" , "Fulfil" , "fit" , "Retort" .)
