I told someone about chickensmoothie and they tried to join, but it gave them the message that they were too young. What happened to COPPA players? And they were 13 years old, too. Aren't they allowed to join?
Are you sure they entered their birthdate correctly? The date they enter must be at least 4 years old in order to play.
Oh god. I just realized- I'm sick and spacey today, while I was helping them make their account I punched in that they were born in 2017! Wow! Thanks for relieving me of my spaciness. Oh, my GOSH!
