Many dons to get debanked soon (4)
I believe the answer is:
anon
'soon' is the definition.
(synonyms)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for anon that I've seen before include "In a little while (informal)" , "Presently - or unknown" , "Nameless (abbr.); soon" , "Not identified by name" , "devoid of credit" .)
