I doubt it. People don't mention when they're young (except in some specific cases like this). Young people can't compare things to a time they didn't live so only older people mention their age usually. I'm 17 rn been on the fediverse since 16 or maybe 15 I don't really remember.

Edit: I personally feel actively discouraged from mentioning my age (even irl i look older) not cause of safety or anything but I js feel like I'll be treated differently when people know I'm younger. Its happened quite often to me both IRL and online where I'll notice a distinct shift in tone after they know how young I am
