Whether it's the newly established [Flag of Savior] discussion group or the slightly earlier established [World Annihilation Plan] discussion group, they are all large-scale discussion groups with more than a million membership.
It's virtually impossible to keep information confidential in these large-scale discussion groups.
Hordes of internet fun-seekers join them, not necessarily for "destroying the world" or "saving the world".
They purely join for the fun, to add to the chaos, even to the point of fueling the fire in order to see more heat.
Many fun-seekers join both groups at the same time, enjoying the chaos from both sides.
—Of course, with the emergence of the [Eternal Hostile] mark, the expansion speed of the [World Annihilation Plan] discussion group quickly slowed down.
However, those who are already inside will not just leave simply because they said so.
