In real world, yes Mr. Blonde probably would be removed. But the authority will have to think of ways to frame him to remove him, they can't just remove him without plausible reasons. Like in this war, not using the advantage of an event card does not break any rules that is in effect and thus is not susceptible to being banned unless SG really wants to and finds other ways to accuse him an ban him, he shall not be banned. And these actions are not at all extreme, a extreme action in my opinion would be to quit the event or play with an entirely upgraded deck even though you are not allowed to do so. What Mr. Blonde did is pretty much the the most subtle protest that can still be recognized. As for being so compelled by Mr. Blonde's actions to write a harsh forum post, well, you seems to be the only one, not that there's anything wrong with that.
