Now, im generally against cheating. But I feel like this could have some legitimate uses for many people.
If you can go out and hang with friends and catch pokemon all day, thats great. I encourage that you do so. But there are nearly 48 million players, certainly some of them have troubles getting around for one reason or another. This could be useful for them.
I'm extremely photosensitive, so I can't go out when its sunny. I love walking around on cloudy days or later at night with my husband. (He works late, so we can't go out together unless its midnight) Theres a gym and a handful of stops right nearby, its great. But in the middle of a bright summer day, I can't really leave my house for safety reasons unless I'm completely covered with thick clothes. (Which is impractical when its already 97° out)
This is also great for people with other physical limitations, people with walkers or wheelchairs, people who live so far out in the country that there are no pokemon spawning, People who can't walk around their neighborhood safely without being jumped or being arrested for "loitering" theres a lot of good this hack can do. and since the game doesn't heavily rely on multiplayer interaction, there very little harm it can do. (Since you still need to put in the in-game effort to achieve high levels and high cp pokemon, coins, items and pokemon spawns are all still server based so theres no real upper-hand gained from this hack aside from phisically possible mobility)
I'm patiently waiting for somebody to make a similar xposed module.
