So you are saying everyone is a kid and needs to have limited internet access?
No one cares about you using 100gb, other people use more than you.
It's not all about you.
If you have spare internet usage based on your monthly bandwidth cap, then there is nothing we can do to help you. Go download more crap then, instead of complaining about having too much.
Btw, have fun asking your parents to limit your internet usage for you.
