One starts to wonder, at what point might it be actually feasible to do it the other way around, by whitelisting IP ranges. I could see this happening as a community effort, similar to adblocker list curation etc.
replies(9):
- Blacklisted IP (Google Cloud, AWS, etc), those were always blocked
- Untrusted IPs (residential IPs) were given some leeway, but quickly got to 429 if they started querying too much
- Whitelisted IPs (IPV4 addresses are used legitimately by many people), for example, my current data plan tells me my IP is from 5 states over, so anything behind a CGNAT.
You can probably guess what happens next. Most scrapers were thrown out, but the largest ones just got a modem device farm and ate the cost. They successfully prevented most users from scraping locally, but were quickly beaten by companies profiting from scraping.
I think this was one of many bad decisions Pokémon Go made. Some casual players dropped because they didn't want to play without a map, while the hardcore players started paying for scraping, which hammered their servers even more.
