I guess one approach would be to tell them that you will be able to see their traffic. Even show them that servers have logs etc. After a time, show them how to use computers more privately, and tell them when you stop keeping logs.

Why would you want to do this? I will warn my children (when they are old enough) about pedophiles and let them know how pedophiles might try and manipulate then, by pretending to be friends or by threatening them or even by convincing them to send naked pictures and blackmailing them. I will let my kids know that no matter how deep they go they can always, and should as soon as needed, come to me or their mother for help. I don't see the need to spy on them or see what they might be searching for or looking at.

I could see this changing if I notice bad behavior. If they're hanging out with bad influences or ordering drugs online or something I might intervene electronically. I'm still undecided about whether to enforce electronics limits (I use mine a lot). It doesn't seem like you should default to intrusive parenting though.
