I think this was asked by someone already, but I do wonder. I think it would be cool if my sister joined the Fediverse (but blocked NSFW content). She is a high school freshman, but I can’t have her join an instance where you must be an adult.
I do have friends on other social medias that are 13+ with their teen siblings making an account to follow them, but what are the rules here??
And that is what I would recommend against, even on a server that does not ban that age. If someone’s (young) age is relevant to a discussion they wish to participate in, I would suggest a throwaway account.
