"King of the Hill"

You were misinformed.
And it's rather disappointing when an experienced player makes this kind of insinuation in his report.

I can't say anything with 100% certainty, but the situation is quite plausible. Although, even with a strong desire, it's not a fact that it can be verified. For example, I'm too lazy to switch scenes during my stream, so I just set it to show the game. If the streamer, in this case, Joisteirs, was playing unfairly, then you can check it by synchronizing the time with the stream. I have absolutely nothing against Joisteirs; I've played with him many times, and everything was always fine.
But remember the idiots who joined Tvarina, Amila, Psih, and Romario's streams and spoiled things.
