How is this allowed?

then the agrument should be SE themself should put a marker on peoples accounts maybe like a purple icon in the adventure plate that will only show up if you are 18+ only and u get a yellow icon if ur under 18, I mean SE does ask how old you are that way every club can easily follow it there you go

Sure thats a solution i guess.
But still... that is not this game's purpose. It is not a nightclub simulator xD
Engage with the game. Clear ultimates. Do raids. Get crafter relics. Do the content the devs provide. Interact with the REAL game. Or go into REAL nightclubs irl.
What is so appealing about dance emote spam and talking dirty to each other?
