While I don't disagree with you, at least in the UK, possession in a cache and in some circumstances, transmission of child abuse images is a strict liability offence, meaning intent doesn't come into it - I suspect it's the same in many jurisdictions. It's a ridiculous position, but it's still the reality for many.

Are there any actual cases where someone was found guilty just for operating a computer/router/whatever that relayed information?

What is a piece of legislation says and what is actually "law" is often not the same, as the courts can interpret it however they want.

There are a couple that stick in the back of my head, but I can't remember the names - I'll try and dig them out when I get home next week!
