I think I might have misunderstood the business model. I was under the impression that you essentially 'scrape' or 'steal' content from other sites and torrents to publish on your own platform—which seems to be how most tube sites operate. Isn't that the reason for all the DMCA takedown notices?
In my country, that is far from legal. You might fly under the radar at first, but as soon as the site gains any real traction, you’d be in massive legal trouble for large-scale copyright infringement. We are talking about house searches, being charged with forming a criminal organization, massive lawsuits for damages, and likely even money laundering charges. In Europe, people receive long prison sentences for these kinds of operations.
