Cold-shoulder — I, Socrates (anag) (9)

I believe the answer is:

ostracise

(Other definitions for ostracise that I've seen before include "I, Socrates may exclude from group" , "Banish, blackball" , "exile" , "Banish from group" , "Blackball, send to Coventry" .)

I've seen this clue in The Guardian.
