Who's Clicking Who Please Don't Sue

In noticed the following disclaimer on click fraud software supplier Who's Clicking Who website.  I wonder if they had a visit from a certain search engines attorney?

WhosClickingWho?™ Independent Auditing Service is a tool developed solely to help identify abusers fraudulently clicking on Pay-per-click listings, and in no way implies any abuses by the Pay-per-click Search Engines themselves. We believe legitimate Pay-per-click Service companies are also as keenly interested in preventing fraudulent click activity as their customers are. PPC Audit Inc. makes no assertions as to what constitutes fraudulent click activity. Such determinations are to be made between the PPC search engine user and PPC search engine provider, based on the user's data provided.
