Wow and thanks for that! After I thought more, I wondered if maybe the wonderful programmers here could simply add a requirement that simply limits downvoting capability to those with say minimum 30-40 reputation. That would require the spammy downvoters to participate in a legitimate way for at least a while, and then also remove that power from them when they abuse and get downvoted themselves. It would also keep them from just creating new bogus accounts to downvote from. Many I've seen are in the negative reputation numbers, and I wonder why they are allowed to stay.
