No. But I understand what you mean, some 13 year olds do squeak more than I think they do... unfortunately. But I already am definitely considering at least changing it to 14. Not a big change I understand, but at least I'll have less squeakers wanting to join lol.
Honestly though, I don't have that many but 1 or 2 squeaky people in my clan, & I'm going to kick them out because their voices sometimes make me want to shoot myself through my ears.
