I work for an ISP and mails for abuse@ and friends end up in my mailbox. Occasionally, there's a "legit" one that I need to look into but the majority of them are automatically-generated reports that some IP address in our netblocks port scanned them or something stupid. The first one gets ignored, the second one usually gets a response from me to the effect of "please stop sending us these automated notifications", and the third one gets the sending mail server's IP address added to my local blacklists. My favorite ones to ignore are from a company who allegedly represents Viacom, Warner Bros., TNT, etc., keeping me up to date on what our customers are torrenting.
