This website is accessible as a service on each of the individual large anonymity networks allowing users of those networks to not leave their network of choice. Whereas normally, members on a Tor Onion Service web forum would only be able to communicate with other members using that same Tor Onion Service, on here, they can interact with members using the website via the I2P eepsite service, or the regular internet, even.
