I am concerned about that implied definition of "voters", and the "they get what they deserve" throw away.
I think it's more "in the unlikely event that people go crazy and vote for this person, they get what they deserve". I, and I think most people, expect the community to vote sensibly.
Wikimedia UK is meant to be open and inclusive (please correct me if I err).
Hence, the ins and out of Wikimedia, Wikipedia, WMF, ARBCOM, checkuser, Commons etc, etc may mean very little to a diligent editor who works away at articles from time to time.
Wikimedia UK should involve everybody, not just the hardened old timers, admins, and the cognicenti.
Indeed, which is why we need to make sure voters know what's going on. Perhaps the election committee should make a brief statement on this user's candidate statement and questions section explaining that they've been blocked.
