Adventures in Motherhood

OK, anyone know how to delete someone who has added you to their friends list?  At least 2 LJ users have added me as their friends without my permission and now apparently have access to my blog.  How do I remove them?  When I go to my friends page, it doesn't seem to be an option?  The users who have added me have spam on their LJ sites, so obviously I don't want any part of that.

THANKS!

OK, experience LJers.  How do you remove someone from your friend list?  Someone friended me and I don't know who the person is.  How do I block that person?  Am I able to?
