Just checked my own steam account and of the 3 groups I'm in, at a glance I have NFI why I'm in 2 of them or when I joined. Simply not a feature I ever use, the exception being one friend group from a half decade ago and possibly there was a steam "quest" during one of their sale events?
It's a bit sus but I can understand why some sperg who openly plays games with other internet spergs ended up with wierdos on his friend list. Group is a bit harder to explain but for all I know it's the exact same popup and it was an accident.
I'm sure Ralph will have fun with it , and I assume someone is already catfishing him pretending to be a german pedophile ready to drop the hot goss on Flamenco. Anyone know what Kraut is up to?
