I don't actually believe korner was hired by nChain or whoever to run the Bitcoin SV account, though I can't rule out the possibility completely. He's certainly not very knowledgeable about BSV, at one point claiming that half of Satoshi was a bunch of "barefoot Indian coders" (while the other half was Craig Wright, obviously).
I think what's more likely is he has a lot of fun roleplaying as the voice/community manager of different coins, exchanges, and companies. His long-standing goal is to be as disruptive to the forum as possible -- posters of the Russian local board will attest to this.
As far as complaints on Meta about it are concerned, I don't foresee that actually being a problem, but more like entertainment. What rational argument does a banned user actually have for being allowed to engage in ban evasion?
In this thread I'd like to build a solid case that Bitcoin SV is korner before reporting Bitcoin SV for ban evasion. I was kind of hoping some members from Russian local could chime in with something I may have missed before proceeding.
