I say leave the sods alone
Nearly all of these so-called "tactics" can also be viewed as a benefit to the consumer, or, at least no worse than standard retail practices at brick-and-mortar stores.
If the sods can't resist the pull of adverts that demand them to "buy now, only one day left!", then they get what they deserve. Some people need repeated painful lessons to cure their stupidity.
BTW, one-day sales and behavioral based adverts are things I see as a benefit. Amazon regularly suggests items that I really *DO* want to purchase, and NewEgg has some killer deals on on-day sales. The trick, as any rational adult knows, is to not buy things that you don't want or need. If I see a hard drive for 50% off the best price elsewhere on a one-day sale, and I need it, I'll snap it up. If a book is suggested to me, and, after I read reviews and some content, I decide to buy it, how does that differ from walking past the bookseller's shop, seeing a book in the window, and walking in to buy it?
We must be very, very careful about what we ask for, lest we find ourselves in a wasteland where all consumer information is published by the government...the only place that this type of enforcement ultimately leads.
