I've been going to the local library practically everyday since the game came out. The last couple weeks that I've been playing the players that meet up at this library have been having the suspicion that this player, HB0007, was cheating but no one was able to gather any evidence.

Well, last night it was storming out and everyone was in their cars. I was sitting in my car catching pokemon at lured pokestops near the library when I noticed that the gym at the local baseball field was being trained. i thought this was very suspicious as it was raining, and 1 am. so i raced over and found that not a single soul was there but somehow was still being trained. I took several screen shots and a video.

the gym before he put his pokemon in:

i was angry and took a very short, directly to the point video, "its raining, its a baseball field, its 1 am in the morning, there's nobody here."

i sincerely hope this is enough evidence to have this spoofing cheater banned, every night him, as well as a few other mystic players, will go around knocking out all the gyms with no evidence of them ever being there. tonight I was finally able to get proof that at least one of them is spoofing.

the gym in question is found here: 41.923152, -88.133624

you cannot reach the gym unless you're are parked in a car in a specific area, or walking near the gym.
