Apdo has been one of the top Korean solo queue players having reached number on the ladder during season 3 and number 2 in season 4. He is well known among Korean players for his ability to win lanes, even against professional players, and for his overall knowledge of the game. Being a top solo queue player, he is also well known for being able to play nearly every role, but is a particularly revered as a top-tier midlaner. He has at least 4 accounts: Apdo, Dopa, Dopa0, and Tar ar ais. He uses his ability to carry games in solo queue to offer elo boosting on the Korean server. His elo boosting services, along with in game trolling, have led other players to loathe him. He has even gone as far as to decide if he will win or lose on purpose depending on the other players in the game.
He had, during early season 3, received a team offer from CJ Entus Frost, but declined it, stating he gains more money by elo boosting than he would from going pro.
However, he, alongside some friends, created Team Dark to conquer the OGN championship. The team was met by the Korean community with mixed feelings, as many did not want them to compete in the professional scene because of Apdo's past in-game behavior and elo boosting. They were allowed to compete and made it to the group stages where they were eliminated.
Riot Korea ended up banning Apdo for 1000 years because of his elo boosting service. A girl, famous in the Korean LoL scene for wanting to seduce pro players, had a crush on Apdo. Apdo who, at the time, had a girlfriend continuously refused her advances. The girl went to his elo boosting service to ask him out, but he ignored her leading her vindictively give Riot Korea proof of his elo boosting business. As a consequence, his main account was banned until 3013 and he received a 2 year ban from competitive play. This ban became the main reason for the creation of many alternate accounts.
September 30, 2014, during a trip to China, he reached rank 1 on the Ionia server, on his account Dopa 丶 YY90888. His record was 197 victories and 63 defeats, a staggering 75% winrate.
