when you order an identical pair of hiking sandals from the manufacturer after the old pair lasted three years, and they start sending you advertisements for more hiking sandals every three days
@0xabad1dea similarly Amazon: you ordered a washing machine, you must want to washing machines all the time now, clearly a big fan of them.
... or look up "how do I repair a broken tap" to be flooded with adverts for broken taps on sale near me.
@0xabad1dea So you have to sit through 365 ads before you get your new sandals?
