Means of identifying bugs cracked by social media firm (4,4)
I believe the answer is:
name tags
'means of' is the definition.
'name tags' can be an answer for 'means' (I have seen 'means of identification' mean 'name tags' so perhaps 'means' could also mean 'name tags'). I am not sure about the 'of' bit.
'bugs cracked by social media firm' is the wordplay.
'bugs' becomes 'nags' (I've seen this in another clue).
'cracked by' indicates putting letters inside (to crack can mean to create a divide in).
'social media firm' becomes 'meta' (I can't justify this - if you can you should believe this answer much more).
'nags' placed around 'meta' is 'NAME TAGS'.
'identifying' acts as a link.
Can you help me to learn more?
(Other definitions for name tags that I've seen before include "means of identification" , "They help to prevent loss" .)
