Something similar to 4chan it looks like.. Guess you could always just download the Tor onion browser & go dark if that's your cup of tea.. Although, as the CIA developed Tor for back channel communications, just how dark it is is anyones guess..
Someone has read to many conspiracy sites...
The CIA is not involved with the Department of Defense: DARPA and the DOD have indeed been involved with starting Tor and supporting/subverting it. But that has little to do with the CIA!
