Does it seem irrational to anyone else here to say
“We don’t know how to prevent this person from using his account to post new downvotes and we don’t know how to reverse the downvotes already posted”
when the actual situation is
“We could stop this account from posting new downvotes with 5 minutes of admin-effort and we could reverse the effects of the mass-downvoting with about an hour of admin-effort without having to write a line of new code, but we won’t.”
It’s a Schelling point. If you can log on as a user you can do a lot of nasty things and we would rather that admins not do those other things.
