So what do you run ???
To run a content site you either:
1) make it
2) buy it
3) license it
or
4) steal it ( you may call it something else, but it is a theft)
And that is the single reason you are getting DMCA take down notices at 3 AM...
So, explain yourself better or live with the accusations
BTW your crocodile tears about tubes ruining your income ? We all have such a story. Mine is the demise of VHS cassettes and rental shops....Yet we "re tool" change the business model but do not steal...
