When Remus Lupin became of age to attend Hogwarts, he was afraid that he would be unable to due to being infected by the werewolf Fenrir Greyback . However, Dumbledore, being fair, believed that as long as special precautions were taken, there was no reason why Remus should be deprived of his education. As such, Dumbledore prepared the Shrieking Shack as a place for Remus' monthly transformation, with the Whomping Willow as guard. This would forever earn Dumbledore Remus' gratitude, as many other headmasters would simply forbid the boy from even setting foot into the school. When Severus Snape found out Remus' secret, Dumbledore forbade him from repeating it to anyone.
In their May 2004 issue, the US Army publication The Preventive Maintenance Monthly , which instructs soldiers on how to maintain their equipment, featured a spoof comic based on Harry Potter , featuring a character named Topper who resided at Mogmarts School under Professor Rumbledore.  The publication received notice from Rowling's lawyers that the comics breached copyright, though the magazine's editor, Ken Crunk, claimed that no violation had taken place, as "[t]he drawings do not look like any of the characters from Harry Potter ".  After a discussion with Rowling's representatives, the magazine agreed not to use the characters again.
