You cannot be held legally liable for reading a contract if it is presented to you. If ToS is meant to be a contract, then no. However, minors cannot consent to a contract, so it would fall on their parents to enforce the contract on the minor.

However, if the ToS is meant to be law, then yes. But courts are known to throw out ToS sections that are written in bad faith. Anything like weev and Aaron are far edge cases with big money and names behind them. Hearst and the DoJ would be highly unlikely to pursue even civil action for breaking the ToS.
