Obviously, they do. They’re quite common to the point where bot-makers are fiercely competing with each other to produce the best, most functional ones. Nowadays, sites such as Nike, Adidas, and YeezySupply release new products using a raffle-based system. In other words, each individual buyer is placed in a queue, and a few people get randomly selected to get the product. This sounds like it could destroy the purpose of bots. However, on the contrary, bots can be used to include mass entries into raffle queues which greatly increases your chances of grabbing some neat sneakers before they sell out.
