In the past I reported massive amounts of spam to SpamCop [1] but it only helps the businesses that utilize data from SpamCop. Some do this transparently in the background so it's hard to say how effective it is. I used SpamCop, UceProtect, SpamHaus on my servers so it helped me. I also accepted the fact that by reporting them with full headers also increased the spam sent to me but I was OK with that.
