Suck my nuts, spammers

Subject:

I had to shut down comments from unauthenticated users yet again today, after seeing that I'd amassed several hundred nonsense spam comments in the last week or two (and peaking in the last couple hours at a few dozen/hr). I've gotta say, what's the point of spamming without any links, and without any readable text? Am I missing the next great thing in marketing? Is "kjkajhajslhd ahjahsdk jahksjhad hajskdhg" Romulan for "BuYz V1AgR09a N0w!"?

Now the decision I have to make is - do I throw caution to the wind, and upgrade to Drupal 4.7 without testing, so I can start using [w:captcha|captchas] on comments? Or do I use the time I could otherwise spend watching yesterday's Simpsons season premiere awaiting me on the POS Comcast DVR dutifully replicating my install and testing the new version. Hmm...

How about neither. Y'all (or youse guys, if you prefer) are just gonna have to register if you want to post.
