IAP stands for 'in-app purchase' or in this case 'in-app purchaser, and in this context it refers to a player who buys hundreds upon hundreds (and some even buy thousands upon thousands) of crystals for real money to be able to build a stronger deck and become more competitive in tournaments by invoking spirits that a non-IAP player has a very low or non-existential chance of obtaining.
