Pervert portrayed as exploitative (9)
I believe the answer is:
predatory
'exploitative' is the definition.
'pervert portrayed' is the wordplay.
'pervert' indicates an anagram (I've seen this in other clues).
'portrayed' with letters rearranged gives 'PREDATORY'.
'as' is the link.
(Other definitions for predatory that I've seen before include "Preying on others" , "Portrayed as exploiting others" , "Killing and feeding on others" , "Living off other animals" , "Seeking to exploit others" .)
