Cheats receiving criticism for such nonsense (12)
I believe the answer is:
fiddlesticks
'nonsense' is the definition.
(fiddlesticks can informally mean nonsense)
'cheats receiving criticism' is the wordplay.
'cheats' becomes 'fiddles' (fiddle can mean to cheat or defraud).
'receiving' is an insertion indicator.
'criticism' becomes 'stick' (giving someone stick is criticising them).
'fiddles' placed around 'stick' is 'FIDDLESTICKS'.
'for such' is the link.
(Other definitions for fiddlesticks that I've seen before include "Expression of annoyance or disagreement" , "Violin bows - rubbish!" , "Bilge" , "tripe" , "Bother!" .)
