I used to use individual email addresses for every site (I run my own email infrastructure, so it's easy). To be honest, didn't really see much of any spam to the site-specific accounts so after a few years I got bored of doing it and mostly use my primary address everywhere these days. For the large sites like fb, linkedin, twitter, etc I do use unique emails. Not so much for spam, just to compartmentalize them away from my primary email so they don't have it.
