ICANN did the following study using fresh listings from SpamHaus DBL, grabbed the whois for those domains, then examined for privacy services to obtain "census" data, to "better understand the wide variety of issues and the potential implications on policy".

>>The 20% privacy/proxy service is nearly identical to what NORC reported several years ago. Allegedly illegal or harmful activities were only observed for 18 out of the 1,600 domains (1.1 percent)."
