Magazines have been doing this for years. They suggest that they have a motorbike to give away in a competition, usually something that nobody wants to buy. They ask for your email address/your home number/your mobile number. They then bombard you with communications to get you to buy a subscription to their magazine, with the bike staying as part of the magnet to get more people to give away their details. Eventually the bike is given away to someone who does not really want it & sells it for whatever they can get for it.
Bridgestone did this with a tyre gauge tool offer recently. When it didn't arrive for ages I contacted them demanding that they remove my details from their database as it appeared that they had garnered my information under false pretence. I received my tool not long afterwards, but I have heard nothing from them since.
