Auto Add to Cart bots (ATC/ADC) Usually a script or extension file loaded into a browser that automatically selects your size and adding to your cart. This is probably one of the most common ones, I have played around with a few of these. They are straightforward, usually they require minimal programming. You program the size and when the page of the sneaker is released it will automatically select your size and add to cart for you to check out. This eliminates the precious seconds of the user selecting the correct size and hitting that add to cart button.
Twitter Scanners Bots This bot sounds is pretty straightforward too. Especially for Nike, a lot of things are TLO (Twitter link only). It constantly pings twitter based on keywords to obtain and launch the link for the shoes. Twitter's API has a request frequency threshold; meaning, you can't just constantly ping it for feed updates, it's throttled, and they will suspend your API key if you exceed the limit. Meaning depending on how its written it can be ineffective. This can also be super sensitive too.
Basically needs to be able to create me a script to get the latest nike releases.
