What's wrong with @YouTube ? Somebody claimed copyright on a video which is just me spinning a fidget spinner for 1 minute
No wonder the big YouTubers are pissed. @TeamYouTube #demonetizedpic.twitter.com/sSgs2KyaEi

Thanks for your screenshot. This doesn't appear to be a copyright strike, just a content ID claim. Here's more info about the difference: http://goo.gl/UVrqiL . Also, claims are not accompanied by copyright strikes, and don't result in suspension or termination of your channel.
"Just a content ID claim." For no apparent reason. But the video was nonsense anyway, so it's gone.
Did you have music in your video? If so that could be what was claimed. If it was, then I suggest using royalty free music to avoid claims, YouTube has a free audio library with hundreds of royalty free tracks. Best of luck
