I managed to get my YouTube account shadowbanned from Ian's channel after leaving some comments that IIRC weren't very flattering towards Poland or Ukraine under the FB Łucznik tour video. I verified that no matter what I post on his videos gets hidden, and checked just now that that's still the case, and I doubt he has jannies doing it for him, so he most likely personally banned me from his channel over differing opinions. Which, by the way, is a dumb move as negative engagement still counts as engagement on YouTube, so letting a single comment chain turn into a politisperging bloodbath that you personally don't like where half of the replies get autohidden by YouTube is overall a good thing for your channel.
I have a sense that Ian has the potential to become a lolcow if he doesn't learn from his mistakes to shut the fuck up and realizes that the good will he has today as Gun Jesus is fickle, not permanent.
