The dark patterns of online sellers to get more of your money

4 August 2025

An all too long list of what NSW Fair Trading, the consumer protection regulator in New South Wales, Australia, describes as dark patterns encountered by consumers when transacting with goods and service providers online.

Sometimes vendors will add extra, usually unwanted, items to an order. Or a business will make it difficult to cancel subscriptions by using confusing language. Sometimes a seller might suggest stocks are low of whatever a buyer is viewing, encouraging them to buy before it’s “too late”.

One thing that especially ticks me off when looking at something I might want to buy is a pop-up, that blocks the screen, offering, say, a five-percent discount on the item. If an order is placed immediately. And I haven’t even worked out if the product is suitable yet.

They’re like those blogs that spawn a pop-up seconds after opening a post, urging readers to sign-up for a newsletter, before you’ve had the chance to read a single word.

Another insidious ploy is confirm shaming, where a shopper is goaded into making a decision by potentially embarrassing them. For instance, an option to decline buying a guide to keeping fit might say, “no thanks, I’m not interested in keeping fit.” The list goes on. It’s a jungle out there.
