Comments are re-enabled after I identify the spammers' IP addresses

I had 41,000 spam comments in my photo gallery. I had thousands of unpublished spams on my blog here. Spam comments were showing up as valid keywords attracting traffic on Google searches. So a couple of weeks ago, I shut down commenting in MovableType. It turns out that one other problem, mt.cgi consuming 2 G of RAM and all my processor time, was a separate issue. ImageMagick is NOT optional in MT 4.2. I had installed it, but MT couldn't find it. Thus an infinite loop consumed all my resources through our favorite cgi-bin, mt.cgi. Fixed that, but what about comments?

I didn't think Gallery was popular enough to be targeted by automated scripts. I thought CAPTCHAs could stop them. I was quite wrong. I upgrade Gallery to 2.3 and got me a WordPress API key for Akismet, which I'm now using in MT and Gallery.

I also looked at my logs, and found that 99% of my Gallery spam comments came from a limited set of IPs. Since I started blocking them at the firewall, I've seen 13,000 attempted hits from them. Here they are. If you're running Gallery, ban them now.
