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??
Mine, sh.itjust.works is 16+.
There’s nothing stopping your sister from just not mentioning her age, but 13 is pretty young for this kind of social media, in my opinion.
