Youtube's automated systems are once again causing trouble in ponyland. Brony Youtuber Magiepony recently had one of her Undertale songs stolen. The person that reuploaded then filed a copyright strike on her channel, saying it was theirs. Her channel has been locked to only allow videos of 15 minute duration.
As she points out in the video, Youtube really only ever notices these things if people make a fuss. So go do it!
You can find her explanation below the break.
