Look I gotta cut to the chase. There's a bunch of dodgy proxy providers out there selling cheap residentials that are basically dead pools or shared from some VPN farm. You buy into those and you're just throwing cash into a black hole. The speed is garbage, you get blacklisted quick and forget about anti-detection. It's like running your bot with a neon sign flashing 'Hey I'm a sneaker scalper.' Do yourself a favor and stay away from those shady cheapies or you'll spend more time fixing broken setups than actually hitting shoes
