Group

okay, so i would like to ask if u add these things ok. ok so when my friend tell me to join the group and it has so many NSFW contents without warning. and when i try to leave my friend keep forcing me to join that group but when i refused, he can let me join easily. im not talking about a group server ok but im talking about a server where you can add them easily without link to copy and send it to them and join, understand? ok so i want you to add a server permission (not group server) where you want to add your friend to the server and then there is something pop up on the screen says "Your friend have server permission on, if he/she choose accept then he will join instantly" hope you understand what im saying and sorry for my bad english.
