"If tomtom included a button labelled `find my ex` and maybe `find closest hardware store selling knives` then YES! That's the difference, what is it with people that can't understand the difference between copyright material being available from a search, and designing a search specifically for finding copyright material."
Even if your Tomtom did have the ability to locate your ex and even if it did direct you to the nearest hardware store that sells knives, why would that be illegal - and it's most definitely not an infringement of anyone's copyright?
I can see how it could be useful to get directions to your ex's house. Maybe she's invited you over for Sunday Lunch - perhaps to try to reconcile your failed relationship - but she doesn't have a carving knife so wants you to pick one up on the way. Your future happiness could solely depend on your knife-wielding abilities in the dining room.
Of course, you could use that information to sneak into her house and slit her throat whilst she's sat at her dining room table (maybe you disapprove of her new partner, or you can't afford the maintenance payments... who knows?). However, Tomtom isn't responsible for the actions you chose to take once you'd located your ex and had bought a knife.
I think that indexing sites - whether that be search engines like Google, Bing (hahaha... as if anybody uses Bing), Yahoo et al, or NZB-specific sites such as NewzBin, Binsearch, United Forums, Merlins Portal, NZBIndex.nl, NZB Matrix, etc... etc... etc... - should be treated in the same manner. It shouldn't be illegal for any of them to provide me with details of stuff; it should be illegal for me to commit a crime which I may have been able to do using that info.
It's not illegal for Tesco to sell me a knife, but it's illegal for me to kill your ex with it. It's not illegal for me to tell you to drive on the motorway at 120mph but it's illegal for you to actually do it. It's not illegal for me to explain that you can rob a bank by wearing a stripey t-shirt and a pair of stockings on your head and brandishing a sawn-off shotgun, but it's illegal....... you get it?
