If someone's account is rated as under 18, will the bots they've posted be deleted?

If someone's account is rated as under 18, will the bots they've posted be deleted? I have some accounts belonging to users under 18, but they post great bots, and I really enjoy using them, so I'm worried I'll lose these bots just because the account user is under 18.

It would be a real loss because some of these accounts are popular and have many chatters and followers.
