Quoting Guy Chapman aka JzG guy.chapman@spamcop.net:
Anyone who's suggesting that the consideration of an Banned User's views matters. So, for a specific example, which I promise I really wasn't TRYING to dredge up-- let's take your ANI post when you indefblocked PrivateMusings. You listed one of his disputed edits as: and HERE SUPPORTING AN EARLIER REVERT BY A JON AWBREY SOCK.
Yup, repeating edits made by sockpuppets of banned users is a problem.
Up to a point. If the editor has made a good point we may wish to discuss it even though the user is banned. And I've seen (I forget with whom, so don't ask me for the dif) at least one case where the insistence on removing banned edits led to a ridiculous result- the sock had fixed a spelling error in an article and then people reverted it and insisted that it stay reverted. I have trouble seeing what that accomplishes.
