Except that Lance Priebe himself said he specifically made Club Penguin to only “appear to be social” with a lot of the multiplayer interactions directly designed to be superficial and emphemeral - making it easy for kids to pop in and away without any significant time of talking and with props and items designed to distract from conversation. This was on purpose - as moderating a kids chat rooms was expensive and logistically inherently difficult to prevent grooming etc.
TL;DR Club Penguin wasn’t really a social site.
