You must be oblivious of the music pirate community and how active and how common place it was, and how it is still relevant today. It's not just based on public trackers like the big names you know. They don't rub that in your face, but pirates have their own secret world hidden from view, you will not find it unless you are part of the community. There are private trackers and usenet groups specifically for Music, which you won't be able to access. The gate keeping is to keep people exactly like you, out. For real pirates, you will never get their IPs in a swarm, and they never get DMCAs. Those public trackers and search engines are there for the occasional pirates, they are not long-term users. If they are not lazy or tech-iliterate users, then, they would always torrent over a VPN, which shields them from DMCAs on public trackers. They may use certain types of remote downloading services, so their true IPs are never shown to the public trackers. They can then use sFTP or other transfer methods to fetch the downloaded files to their personal computer. Users who seed for long term, rip and release torrents are never on public trackers.
