Sure, but you still shouldn't be selling the technology as actually working, instead of developing.
Amazon bought whole foods a while back. What would have stopped them from just collecting the data in their own stores, and then developed the tech?
Hint: shareholder value.
Little bit more.
Someone made 3 servers, then a bunch of accounts on those servers, then used all of those accounts to downvote.
Allegedly because I ain't got the time to manually verify that myself.
