How to install adblockers, how to detect fake download sites that give you computer aids? Show them how to use a VPN and choosing the right one (a true pirate must always choose a VPN with port forwarding capabilities, so you can still seed) I feel like this is all valuable info we all learned as pirates the hard way, and valuable information to pass on to our kids.
Absolutely, I would say whether you're teaching piracy or not, those are essential things that everyone online must know about; it would be unethical to allow your kids to go online without that protection.
