So about 24 hours ago, Niantic (developers of Pokemon GO) shut down about 90% of the sites that allowed users to search and reveal Pokemon near a given geographical coordinate. None of the sites had "Pokemon" in their domain name, and PokeVision, the most popular Pokemon tracker stated that it was "respecting the developers wishes". How do they do this? What possible leverage could Niantic have over all these sites to make them suddenly "respect their wishes"? Many of these sites were monetized, and you guys know as well I do that nobody takes a site like that down unless they have to.
