While true, the only way to really stamp it out temporarily is to get strict on censorship, say auto banning or jailing anyone who say "www." but then the tactics switch to "vvvvvv." or such and just on and on. I think a super mall is a bit of a better thought on it, so many places to go and see and do that they could be hiding anywhere whispering the goods that even if you had good security they may overlook them as a normal person but if you have too much security you make your normal guests or customers uneasy.
