He could of just grounded her, sat down and talked to her, or banned her from using the internet like any logical parent and that would of been just as effective and less embarrassing. No form of punishment should ever leave a negative cloud on you for the rest of your life. Imagine her trying to get a job and her potential employers see this, what if she gets bullied relentlessly for this. If your going to upload your kids' mistakes for the whole world to see and criticize when your a parent, I feel sorry for your kids.
my moms beat me in school, in the grocery store, in church... thats the type of mom she is, she shows she doesnt tolerate that and would not allow me to embarrass her, fu*k how i feel, shes my mom not my friend. If you just ground em for talking to a 19 year old pretending she 17 like she aint take out the trash then she isnt going to take you serious and walk all over you and you are going to smile like everything is gravy.
