As an active player in the game, from my experience, it will take at least a week to move through 80 ranks and prestige to the next level.
There are 15 prestige levels, and to prestige, this means that you must play a certain amount of matches and earn XP points to move on to the next rank. For example, in the game Call of Duty: Modern Warfare 3 there are 80 ranks you need to play through to prestige. Instead of playing the game continuously and ranking up like regular people, they just initiate a hack to where their accounts skip through the ranks and become one of the top ranked gamers.
The second reason is that perhaps that individual is taking a really long time to either get to a certain level they desire. The first reason is the people committing these hacks just don’t want to pay for the downloaded content. There are a number of reasons why such an individual would want to hack an Xbox Live account.
