Time for Another Stupid Newbie LJ Question

[the_other_sandy]

I just got my first ever spam comment (on a post I made back in July). I know how to delete comments, but I'm pretty sure I've seen some people mention there's a way to block certain IP addresses from commenting in order to prevent this kind of thing from becoming a problem. Does anybody know how to do that?

Yup, you BAN then. That keeps the trolls away. I've done it once.

I've never done it (ban somebody), so I can't help you out on the finer details, but maybe this from the LJ FAQ will help:
