I don't have a problem with the cheating.
For full disclosure, I run a service for the game (leveling/boosting), so obviously I'm pro-cheating.
Anyways, the game isn't competitive. Me being level 34 has no impact on being level 23. Yes, gyms exist, but they're incredibly easy to defeat and the diminishing returns of leveling up are easy to overcome. 6 of your pokemon could beat 1 of mine.
I do have a legitimate account that I haven't cheated on whatsoever. I enjoy the exploration, but I also enjoy automation and that sort of stuff, so I have 4+ illegit accounts
