Is anyway all nonsense in Opensim. Never met somone younger than 40. lol Average age is 60.
In SL it makes sense. In the early years of course. There were teenagers in second life when it was new. But now you will only find teenagers in Fortenight (average age 27 yo) or other games.
What would it mean then for Americans if they are under 21? In Germany you are adult as 18 years old. In USA you can go in adult shop when you are 21 yo or in a Pub and drink alcohol.
In all other countries in the world you can go at the age of 18 in an adult shop or drink alcohol even with 16 in a bar or Disco.
It is all nonsense and made perverted what Americans made out of opensim. OSW is just a typical prude american website. There is no need for such. We write in Fediverse or Facebook anyway more.
