-- It's fairly easy to detect (that's not the issue), but getting rid of the likes seems a bit harder (just using core methods)
I'm not really sure this is a bug or intended, but when you delete a user, their likes aren't deleted.
I think I've run all the crons and cache rebuilds
Should a users likes be deleted when the user is deleted?
(Also, should a users likes be temporary-deleted when the user is banned .. consider accounts that are permanently banned to stop the user re-registering using the same account details?)
(Also 2, you are left with a like under the content, on clicking the user.. you are presentedwith a warning that the user no longer exists... it's a bit ugly, it would be better if it just wasn't present, since we're deleting the user.. do we care what they have liked )
