On my account on YouTube, someone reported three of my videos with copyright strikes and forced me to take them down. Plus, they forced me to watch a terrible Happy Tree Friends episode about copyright infringement and take a test on it. They then said I could be shut down if this happens again. Should I just delete my account?
Well, it depends what were on the videos.
If copyrighted materials were on them without proof of non-ownership, then I can see why. If there were no copyrighted materials were on them, or they were copyright of you, then I might just dig a bit deeper as to what caused the ban.
and find out who is banning/trolling you.
like Opt1onal says
if you have copyrighted stuff in your videos that does not belong to you then it is just bad luck but that is how it works
if you do own the material/ there is no copyrighted material you should look deeper into it and perhaps inform youtube that there have been a mistake
last time i heard something like this i was told you can ban someones videos by simply faking that you that and that company without actually being it(not sure if it still works that way)
