Quite often now, you see when you sign up that there's a box to be ticked beside a sentence that says, “We will provide this information to other vendors” and you can tick it if you wish to do that.
If you do tick the box, how far does it go down the chain to these vendors or other groups? How about the resale of this data? Does that go on? Does some organization get this data from somewhere else and then in turn resell it to somebody else? Are we concerned that this data gets passed through many hands through the resale?
