"Successfully Reporting GPS Spoofers Method?"

#PokemonGO: Me & my partner took an early morning walk with our dog today and decided to take a level 10 gym down in the middle of the park we went to.It started to rain, luckily right next to the gym, just in range was an old Victorian style seat shelter, so we were able to hide under that. Aside from a couple of joggers going by every now and then, we were the only people in the park.During taking the gym down we were joined by another player, but the gym is in the middle of the park, nowhere near any roads or vehicle access, there was nobody under the shelter with us and I wandered around the gym range and checked behind the few big bare trees, there was nobody else with us (apart from our dog and she isn't allowed to play on PoGo these days).With 100% certainty I can say there was nobody else who had legitimate access to that gym, it's not a park with long grass or bushes they could have been hiding in.We got it down to level 1 or 2, whilst we were healing up, my partner pointed out that it had ''already gone blue'' (we're Mystic), true enough this other player had placed their Dragonite in and it was already being levelled up. We still got to put both our Pokemon in, I wandered around again just to be sure that we were still alone.I took a screen shot of their name and picture of the gym spot IRL.What is the proper way for me to report this?I'm not usually that bothered about people cheating in games, but this is one of those games where I do feel that spoofing and botting is impacting other peoples ability to play (they can load up and hog gyms). via /r/TheSilphRoad http://ift.tt/2l7gmXr
