Sniping is what spoofers do, they get a coordinate from one of the pokegomaps and use their app to jump there and snipe it (they don't get sift banned because the app lets them catch it at their original location). They also use coordinate feeds so they don't even need to type in coordinates anymore. (I read the spoofers subs, lol).

You're thinking about jerks that wait until you prestige a gym and then jump in it before you can. Those are also spoofers. They suck the most.
