Not it legitimately happened and Leon tried to play it off as if it was proof of his high skills, he tweeted how he really was just performing a high number of actions per minute and the game kicked him because of it.
From the actual article (and not this weird one OP posted):
Musk shared a photo of a disconnected screen from Path of Exile 2. The reason given within the photo was “You have been kicked for performing too many actions too fast.”
Musk wrote, “Wasn’t even using a macro lol.” One user replied “hey give us like 10+ active skills and don’t expect us to hit the buttons?!” To which Musk replied, “Seriously… And the penalty for too many clicks/sec is you get executed immediately! I think this will get patched.”
Gotta love the dicksuckers that come rushing in to find a way to blame the game for offending their lord. Of course, to literally anyone with the context and a brain can see he’s full of shit.
