Stop spam now with your gigantic p3n1s!!!

Even though I have the fantastic MT-Blacklist installed on my site, I still get tons of comment spams, both denials that get blocked but eat up resources, and spams for as-of-yet-un-blacklisted sites that eat up resources and my patience. The flood has gotten especially bad over the last few weeks (I'd wake up to 20 new comments and hundreds of denied notifications) so I decided to take a few more drastic measures. I didn't quite upgrade to MT 3.1 yet, but I did follow most of the suggestions "here":http://www.elise.com/mt/archives/000246concerning_spam.php that I wasn't already doing, including renaming mt-comments.cgi, and taking off the comments popup from the link; instead forcing you to the individual entry archive. We'll see how much that reduces the crap around here. Oh, I tried to run David R's "mt-close script":http://www.rayners.org/2003/12/closing_comments_on_old_entries.php to close out all entries older than 5 days, but I kept getting an error about something to do with App.pm, although it is in my cgi-bin folder somewhere. Anyone else seen that before?
