Then that is why your channel has been terminated. End of story.
But there have tons of channel like mine. Their channel is still there.
That's irrelevant. Lots of people break the speed limit or don't pay their taxes. Does that mean it's legal or does it mean they haven't been caught yet?
By definition, you only see the channels that haven't been terminated. What people don't see is the hundreds of thousands of channels that get terminated.
Sport channels on TV pay millions of dollars to be allowed to broadcast sports events like boxing, football, soccer etc. Do you really think they will sit back and let people steal their content and then broadcast it for FREE?
how can i get my channel back.
Your channel is gone forever. You have zero chance of getting it back.
