Nintendo sent the email below to the good people at Suicide Girls. Background here and here.
We would like to apologize to you and to those who frequent the suicidegirls.com website for inadvertently contacting you about a fan posting on the website.
We know that many of our fans are old enough to make their own choice about what they want to view on the Internet. We value the support of our fans and we respect their decisions. The letter was sent as part of an ongoing Nintendo program to aggressively protect our younger consumers from the hundreds of sexually-explicit sites each year that use Nintendo properties to attract children. We are proud of our efforts in this area. Unfortunately, the site posting identified in our letter was targeted by mistake.
As a gesture of goodwill, we would like to offer you (and RuneLateralus) a free Nintendo video game system and game of your choice. (...)
In addition, we would appreciate it if you could provide us with contact information for RuneLateralus, or have him contact us directly, so that we may apologize to him. We would be glad to send him a game and system of his choice through you as well, since we do not have his contact information.
