Using an Elo Boost service is one of the best ways to rank up your account. These services are popular in Counter Strike Global Offensive as well as League of Legends. They work by exploiting game mechanics that should not be able to be exploited. The ranking system is point based. For every win you receive you get more elo, and for every loss you lose elo. You gain and lose elo according to different things in algorithms like the ranks of the players in your lobby or the speed of the win. With the help of boosters who have played the game for thousands of hours you can’t lose. A boosting service will work by having the booster play on one of their higher leveled accounts and another booster from the team recovering your account. In some cases the entire team will be filled with boosters and the single low leveled player. These players won’t lose because they are hired to win. As they gain wins your account gets more and more Elo and ranks up because of it.
These services aren’t necessarily approved by the developers like Riot games. Then again their isn’t much for them to do about it. There is nothing to distinguish a booster from someone who is just playing with one of their lower leveled friends. They could of course check the IP addresses of the accounts and see that the IP isn’t in the norm. This is a lot of effort to go to for something so harmless as a rank increase. If anything developers don’t want to see others profit from their games because of exploitable things in their ranking system. The Elo rating system is found in many games and does an effective job at removing players who shouldn’t be there. Sometimes it results in those players deranking. In order to be the best you need to play the best.
