Problem contributor to blog - time to be banned? (5)
I believe the answer is:
poser
'problem' is the definition.
(I know that poser is a type of problem)
'contributor to blog time to be banned?' is the wordplay.
I cannot quite understand how this works, but
'be' could be 'pose' (posing is a kind of being) and 'pose' is found in the answer.
A single letter 'r' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for poser that I've seen before include "subject for an artist?" , "Difficult problem" , "Puzzling question about ropes" , "Someone behaving so as to be noticed" , "Tricky question" .)
