I didn't know that but it makes sense from a safeguarding perspective. (...?) This is a 13+ game even though lots of adults play, too. Predators could seek younger flights to groom those members. I don't know, though. The opposite argument could be made that everyone knowing everyone else's age mitigates harm, accidental or not. And it's not like most people don't share their ages, gender, and country anyway, so I don't see a problem with compiling the data. Just thinking out loud, though.
