VRmaniac is the name of the forum
The username is: 꼰찌. (Phonetic Kkonjji), which roughly translates as: Lace (or even Braided belt).
But I doubt Google translate has this correct.
VRmaniac created a central buy-in for the Pimax kickstarter. Kkonjji is the force behind that initiative. Users from VRmaniac are backers also, but in a different way. Users wrote in and paid money to VRmaniac which on their turn bought in at Pimax kickstarter. So VRmaniac is address on a lot of headsets for Korea.
Because of the progress being made they want to inform their backers who gave them money to buy the pimax 8k centrally. Thats what the purpose was from that public vid: inform their customers. They didnt know it could be picked up outside their country.
The VRmaniac site still has the urge to inform their users, although they cannot show any vid/clips anymore (apparently). But... They are in awe and almost cannot hide their excitement. Backers also want to see Elite Dangerous tested and Eve Valkyrie. And also DCS comes to mind for a user.
