>>8489chan.tw was originally setup by Joshua Connor Moon of Kiwifarms fame as a successor to 8chan.
He sperged out one day and said 9chan was too hateful (as of 8chan wasn't) and was giving ownership of the board to endchan leadership.
Endchan said they weren't seeing the numbers needed to make it worthwhile and shut the board down. To be fair to them it was a very slow board.
