Novelty account names tend to have references, just saw one the other day where not only did a commenter have the username of "Hitlerly Litler" or something to that effect, but someone pointed it out with the /u/username syntax because they thought it was funny.

If they're doing naive string searches, does every thread that guy shows up in get counted? What about robot_hitler, MeinFurher, and all the others?

Did anyone control for the topic very well? Many of the current news stories deal with fascism, or things people might worry to be fascism or totalitarianism or genocide.
