>BREAKING. Here's the contract 8chan (Jim & Ron Watkins) tried to make Fredrick Brennan, the original founder, sign. It uses language designed to trick him into thinking they'd stop using the "8chan" brand. We now know they were aiming for "8kun", which is... pretty much the same.

This, and the content of this document (which includes an NDA clause) suggests, that the agreement hasn't been reached.
