gwyn | Is there a way to ban an IP address in LJ? (Reply)

I'm getting deluged with spam comments in a couple of old LJ posts. They seem to have the same or similar headings, but they're mostly anonymous (although I've had a fair share of LJ user spam, as well). I can ban user names, but is there a way to ban IP addresses? I finally added a captcha for anonymous comments, which I really hate doing because I have a handful of friends who comment here who don't have journals. But it doesn't seem like there's very much LJ lets us do to unbury ourselves from spam. Man, I really don't want to limit comments to only users or friends.

In the meantime, here, have a picture from Hawaii.
