It won't matter, if they become a big enough threat to powerful interests they will be taken down. The only solutions I see are: hidden service in TOR, tracker hosted in .ru (nobody took down libgen yet and you can bet plenty have tried), or a decentralized solution that can serve metadata over the swarm in addition to torrents.
This is actually part of I2P, there are hidden trackers that are only accessible on the network, and that use the inbuilt Torrent manager that comes with I2P.
.ru was an euphemism, I meant the country [Russia] not the specific .ru tld.
rutracker.org is hosted in Russia.
libgen and sci-hub are using a more complicated setup with lots of fronts (in various countries) run by people who know what they're doing. I believe the backend infrastructure is in Russia.
