Anonymous reformed salesmen (8)
I believe the answer is:
nameless
'anonymous' is the definition.
(similar in meaning)
'reformed salesmen' is the wordplay.
'reformed' is an anagram indicator.
'salesmen' is an anagram of 'NAMELESS'.
(Other definitions for nameless that I've seen before include "Too unpleasant" , "Lacking means of identification" , "Unidentified" , "This undistinguished" , "Too horrific to be described" .)
