I'm too afraid to let anybody into my town, of any age. ._.; I'd really like friends, but you just don't know who you can trust online, you know? I let one person into my town and was having an anxiety attack the entire time hoping they don't trample/steal flowers or chop down my trees or net my villagers!
As long as the person doesn't jack up my town, I'm fine with any age. I'm not much of a talker, anyways.
You can get your residents to change their catchphrases. Go to the town hall and talk to Isabelle across the counter (rather than at the mayor desk). Tell her there is a problem resident and she will ask you if they are saying something offensive, have offensive letters, or offensive clothes (I think those are the choices, anyway).

For me it's a comfort thing. I'm not comfortable adding someone under aged who I don't know well, I think it doesn't look appropriate to their parents. However, if it's someone I've gotten to know and who I get along with, as long as their parents don't mind I have no issue with their age.
