Are ther hackers in this game? there are some trainer/hacks out there. I really hope they don’t work, I have really invested time and money in this game 
There have been instances of people hacking the game through various means. They’ve been dealt with as we find them. Naturally as well, we close loopholes as they’re discovered. We definitely want a clean game for everyone playing.
That being said, if you see someone you suspect of having cheated/hacked, please take a screen with their User name and send it off to mobilesupport@d3p.us and we’ll look into it. We take action as we find them, but being proactive never hurts.
are you aware of a trainer tool that is around? anyway to stop it?
My suggestion is if you’ve found something online that you think is a hack the best thing to do is email support rather than talk about it here. 
lol yeah, good idea, lets not encourage users
Most definitely the case. Please mail support about any such things found, we’ll investigate them.
