If I haven't actaully interacted with a person in a business context I typically do not connect with them in LinkedIn. In Facebook it is people I know in the real world but there may not be a business relationship. I don't link with people I do not know which keeps true spam to a minimum.
Bingo -- I have a facebook account for friends and a linkedin account for business colleagues / relationships. Both serve me very well.
