I didn't have strict enforcement with my kids, and some web content (like a streaming service) was only available in another country at that time. One day my 13 yr old daughter is on another countries service, and I'm like how did you access that. She said "oh I just setup a proxy server connection." Me: huh ok. Friend of mine who had his kids on full internet control is like "OH, shit I better check if my kids can do that." They will find a way :)
