Why are @0xggy and @silverfang88's groups so popular, and why do so many people enjoy chatting in these groups?

In these groups, if you observe carefully, you'll notice an almost cruel pattern: a group with no one posting NSFW images is likely a distant and estranged relationship.
Even in many KOL (Key Opinion Leader) group chats, they often need a few "yellow images" or risqué jokes now and then to turn polite "Hello, teacher" greetings into genuine closeness.
Groups without NSFW images eventually end up with either a bunch of fools fawning over each other or a bunch of fools arguing.
Everyone is just flattering each other, saying nice superficial words.
On the surface, everything seems harmonious, but in reality, no one trusts each other, and relationships always stay shallow.
Just like some KOL groups, where there are big names and smaller ones, many KOLs don't even know each other well, and no one dares to be the first to speak.
As a result, the group chat becomes increasingly dead, cold enough to freeze people to death.
