Finally

A way to get rid of people you don't want to see on your Friends Of list.

1. Make sure you're logged in
2. Go to http://www.livejournal.com/admin/console/
3. Type ban_set username into the console

They magically disappear from your Friends Of list, never to be seen again, nor can they ever comment.

Right - it acts sort of like a permanent filter - they're still there but you can't see them. Since my friends of list is hidden, the only way they'd ever find out is if they tried to post a comment, but I'm pretty sure the ones I removed were abandoned (they hadn't posted in over a year).
