'dodgy deceptions' is the definition.
'false pretences' can be an answer for 'deceptions' (false pretences are deceptive pretences). I am unsure of the 'dodgy' bit.

'faceless rep has ten new' is the wordplay.
'has' says to put letters next to each other.
'new' is an anagram indicator.
'faceless'+'rep'+'ten'='facelessrepten'
'facelessrepten' with letters rearranged gives 'FALSE PRETENCES'.
