'controversial content' is the definition.
I don't know anything about this answer so I can't tell whether this works.

'to save indy cryptic' is the wordplay.
'cryptic' indicates an anagram (a cryptic or obscure order of the letters).
'to'+'save'+'indy'='tosaveindy'
'tosaveindy' with letters rearranged gives 'VIDEO NASTY'.

Can you help me to learn more?
