Excluded, blocked (6)
I believe the answer is:
barred
I believe this is a double definition.
'excluded' is the first definition.
('bar' can be a synonym of 'exclude')
'blocked' is the second definition.
('bar' can be a synonym of 'block')
(Other definitions for barred that I've seen before include "Wouldn't allow" , "Precluded, obstructed" , "Excluded, blocked" , "Prohibited" , "Refused entry to local pub" .)
