Many make certain you get the blame (7)
I believe the answer is:
censure
'the blame' is the definition.
('censure' can be a synonym of 'blame')
'many make certain' is the wordplay.
'many' becomes 'c' (C is the Roman numeral for 100).
'make certain' becomes 'ensure' (synonyms).
'c'+'ensure'='CENSURE'
'you get' acts as a link.
(Other definitions for censure that I've seen before include "Castigation" , "Official reprimand" , "Rebuke, strongly criticise" , "Formal disapproval" , "Opprobrium" .)
