It reads, "A system and method is provided that drives microtransactions in multiplayer video games. The system may include a microtransaction arrange matches to influence game-related purchases. For instance, the system may match a more expert/marquee player with a junior player to encourage the junior player to make game-related purchases of items possessed/used by the marquee player. A junior player may wish to emulate the marquee player by obtaining weapons or other items used by the marquee player."
So basically they are matching people who spend little against those who spend a lot in order to try and "encourage" the freeloaders to dump cash.
