On February 16, 2016, internet reviewer Doug Walker (The Nostalgia Critic) posted a video about his concerns related to YouTube's current copyright-claiming system, which was apparently being tipped in favor of claimants rather than creators despite many of those videos being reported as covered under Fair Use laws. The video featured stories of other YouTubers' experiences with the copyright system, including fellow Channel Awesome producer Brad Jones, who received a strike on his channel for uploading a film review that took place in a parked car and contained no footage from the film itself. In the video, Walker encouraged others to spread the message using the hashtag #WTFU (Where's the Fair Use?) on social media. The hashtag spread among multiple YouTubers, who gave their support to Walker and Channel Awesome and relaying their own stories of issues with YouTube's copyright system, including Dan Murrell of Screen Junkies, GradeAUnderA, and Let's Play producers Mark Fishbach (Markiplier) and Seán William McLoughlin (Jacksepticeye).
