Personally, and this is only a personal opinion, I wouldn't have thought that cookies and contact details count. You don't have an option over cookies aside from avoiding the website altogether and, unless they've bought something or signed up for something, you shouldn't have their contact details.

He tried to get a court injunction and the judge ruled "fuck you, I hate email spam".
