All I know is
Pinzoro fans said Pinzoro has My drug dealer cheat codes, will fight Crydo, will scar Crydo
They called us BS
My drug dealer - checked
And, as far as ZkK is concerned then there are literally manga panels indicating so. No one made this up.
But, I haven't seen anyone who doesn't believe in ZkK to present counter arguments except all they have is "Pinzoro fans are illiterate, delusional and it can't happen because he is side character"
