OK, how far would you take it ?No, partly because of hand-wringers like you.
Trust me - if the penalties for not doing so were so severe that the companies had to choose between not operating in the EU at all, or finding a way to clean up their act, they would find a way.
Would it apply to my local paper having a classified section in the back ? If not, why not ? After all it's pretty well the exact same model - taking a small fee from the seller to advertise his goods, and giving the potential buyer a way of knowing that it's for sale.
And would it apply to, for example, me chatting to a friend and mentioning that I have something for sale, then him mentioning it when he hears another friend expressing that he's looking for that thing ? Eg, some years ago I'd mentioned to a friend that I was looking for a V8 Discovery - he mentioned that someone at work had one for sale.
Only difference is that no money is changing hands - but the friend in the middle has still facilitated the buyer and seller getting together. So should he be liable if there are faults in the car ?
