Ironically the Bitcoin SV account has no actual connection to Bitcoin SV. He knows fuck all about it, and is indeed a banned, multi-accounting troll. He also owns the Bitcoin Gold and Bitcoin Cash accounts but never uses them.
I learned this from my Russian sources, with whom I've been colluding behind the scenes.
Korner is a lot like Garry Kasparov: he plays 4D chess, trolls the government, and all the other Russians hate him.
