Well . . that's different, I'd say.
So those are the links TO your site or coming FROM sites?
If it's TO your site I'd most certainly let those 404, if they don't exist that is what a 404 is . . . for. :-) If those are the sites the link comes FROM, I'd deny the request.
Unless this is some form of attack strategy I'm unaware of, I'd have nothing to offer if that were the case.
