Download Blue Coat K9 Web Protection Admin, it's completely free and it will work even when your child tries to use Google incognito. You can even set it to bark at them when the page is blocked! It makes my son jump with fright every time! lol Yes he's 13 and I have caught him wacking off to porn thanks to this stupid google incognitio mode but I've fixed all of this with K9 Web protection. Always beware of smart TV apps because they have internet browsers laced with porn as well. I've uninstalled the apps and disconnected them from the wifi. It's terrible! My worst nightmare, but even still it could be worse, he could be trying to do what he sees but thank God he is not that stupid! I have resolved the issue as best I can for now.
