Please, don't ban anonymous account, there are at least couple people who regularly use it. It is rare that anyone would use it for voting, it was the first time I have logged in and noticed so much upvoting and downvoting in a single thread. Sometimes I find a couple of votes in a thread, and I often revert them, but that's it. Maybe there were previous incidents in the past, but I haven't noticed them. Of course, things like that relies on goodwill. If someone started abusing it, there would be no choice except to ban it.

By the way, thank you Nancy. You do a job that is often unpleasant, but necessary.
