(v) display any Ad(s), Link(s), or Referral Button(s) on any error page, on any registration or "thank you" page (e.g., a page that thanks a user after he/she has registered with the applicable Web site), on any chat page, in any email, or on any Web page or any Web site that contains any pornographic, hate-related, violent, or illegal content; (vi) directly or indirectly access, launch, and/or activate Ads, Links, Search Results, or Referral Buttons through or from, or otherwise incorporate the Ads, Links, Search Results, or Referral Buttons in, any software application, Web site, or other means other than Your Site(s), and then only to the extent expressly permitted by this Agreement
