IPFS alternative to torrent trackers for pirated media, such as nyaa.si. The file transfers are decentralized but the content index (tracker) itself is centralized. Which is a pretty critical flaw, recently made apparent with RARBG's takedown.
Interplanetary Wayback uses IPFS to store web page archives, although the index of those pages stays on the instance. Seems to be actively developed by a professional team.
Bittorrent is also known for being easy to track outside of private trackers. You're saying IPFS is easy to block and track, but how does that look like relative to bittorrent? Because if it's about even, IPFS still has the advantage of not having a centralized tracker.
