Hi Marcin and again, welcome!
Ya, it sucks that you are now joining in on these rough times, most threads on all forums are about scamming, card banging, tubes, ratios going to shit, all around decrease in revenues and such.
But about what you're talking about, the only ways I've heard is content owners must be VERY VERY VERY..... VERY!!!! active at going after these torrent sites, file upload sites, and tube sites, actively sending DMCA's probably every single day to protect their content. This is the only way!
I think it's becoming probably a big % of their daily work now, for those that actively chase down those thiefs.
Very shitty how in todays world, with technology and all, your example about cigarette store in real, advertising stolen stuff would get shut down immediately, but online those sites are thriving
I do think someday the laws will catch up to these stolen content criminals
