In case somebody flagged your video or it was taken down by YouTube?
Worry not use this method that tested my some experts and got their videos back 100%.
Put this in the bottom of all your video descriptions:
Giveaway Niche: “You are not required to subscribe, turn notifications on or drop a like in order to win/participate in this giveaway. It is ONLY a suggestion.”
Blackhat/Hack niche: “This video is about OFFLINE app modification and is STRICTLY for educational purposes. It has NO effect on any aforementioned company or website.”
That is the safety precaution. If your video is flagged, appeal it and put those same sentences in the appeal message. Feel free to slightly change wording/positioning if you want to, but it is not required.
