Correct, this is the law of GCBTW. Even when it happened to him in World of Warcraft, it was the Final Fantasy XIV community. The FFXIV community is so bad it transcends games. Such devastation is their intention.
Meanwhile, the ones who reported the trolls/griefers to Square Enix were in no way FFXIV players. They were card-carrying members of the sensible and mature Bureau of Asmongold Likers and Defenders (or BALD for short). Clearly, one of them was monitoring the stream to comb for bad behaviour. They must have created an FFXIV account for the sole purpose of reporting the ne'er-do-wells to Square Enix, then promptly uninstalled so as to avoid any appearance of participating in this degenerate game.
