Harasses with membership tokens, I hear (7)
I believe the answer is:
badgers
'harasses' is the definition.
('badger' can be a synonym of 'harass')
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for badgers that I've seen before include "Pesters like burrowing animals" , "Pesters; black and white nocturnal animals" , "Burrowing mammals with strong claws" , "Bullies" .)
