Because Q said after migrating from 4chan [Tripcode and/or comms were compromised] when live and tested on 8chan, that that should be the ONLY form of communication with anons. All others not to be trusted. Then almost two years later, 8ch got shut down (cloudflare could no longer handle the political pressure to censor.) In the video linked here, the 8kun owner (same as 8ch owner, Jim Watkins) said the new Q board will be on 8kun.  Note: I realized soon after posting this that I could have clarified that the new Q board will be one of many boards on 8Kun. Some users here might not be aware. Just like 8ch, there will be hundreds - if not thousands - of boards, with owners (BO). Read subsites, kinda like subverses on Voat. See @ infinitechan on the twatterverse 1 week ago called on 8ch board owners to email them, so that their 8ch boards will be migrated to 8Kun.
