There is no clear answer in this sort of situation I tend towards the view that letting a blocked editor find that he or she can keep creating sockpuppets and having them blocked but it doesn t matter because their edits stay anyway encourages them to keep socking whereas letting them find that doing so is a waste of their time because whatever they do with sockpuppets gets reverted or deleted encourages them to stop doing so For that reason I usually delete in this situation However I can see that there is a case for the view that useful images are still useful even though uploaded in violation of a block so I will not criticise you if you take a different view from me The editor who uses the pseudonym
