The POC is a made up personal challenge that the player must self enforce. The only rule is that you must catch and obtain every Pokémon in each section before defeating the gym leader. All of this takes place on one game. However a lot of players tend to add their own spin on the challenge to make it more fun or challenging. I use a glitch that let's players duplicate Pokémon and items making the start of the game much longer. Some people trade in extra Pokémon to get exclusives and trade evolutions. Some people grind against the gym leaders because they want the satisfaction of finishing the POC, but don't want to put in the extra hours. Are you having fun? Then it really doesn't matter. However if you're gonna post about your times and how challenging each section was; then yeah you're 100% a cheater in my eyes.
