we have had some AfD discussions on people & organizations whose notability arises in large part because of either criticism or attacks they have made upon WP; results varymy own view has consistently been that as part of NPOV we should always in case of doubt be careful not to remove information about those who don't like us.   
 ::But in this particular instance, this is a person who has without malice towards us made the error of hiring a firm whose practice it is to evade the principles of WP; This would fall under BLP policy.  This is minor negative information, not relating to whatever actual notability he might have. Even if he were to have an article, I would not include this materialit's a basic BLP policy that we do not include the misdemeanors of basically private individuals, let alone use them as the basis for notability.
