People doing screen-scraping like Plaid will seek out IPs that look innocuous. One place I heard of had bank of mobile phones all with cellular data plans hooked up to some UI automation. This lets them run screen scraping from a real phone on a real cellular network. Also look at the company Luminati Networks/Bright Data: https://brightdata.com/proxy-types/mobile-residential-ips https://brightdata.com/proxy-types/mobile-residential-ips They pay app developers to install an SDK on their popular mobile apps, then sell the right to run network requests through users devices. Perfect if you want to do some sketchy screen scraping and need access to a lot of innocent looking IP addresses.
