Some People See Kemono Avatars as Underage.
I do not see how one can tell a Avatars RP age based on a Look of the avatar Unless they are specifically Kid Avatars.
Kemono, and Anime Avatars always skirt the Looking Young but older looking Avatar.
My Sim I would not ban a person just because of the Kemono Avatar.
We have many people use the Avatar and others.
Heck one of those Big Werewolf AV's may be a Child I don't know.
