Yes, boosting someone else through League of Legends can be considered cheating and can result in penalties for both the booster and the boosted person. Boosting involves a higher-skilled player (the booster) playing on someone else's account (the boosted person) to artificially increase their rank or rating.
Boosting undermines the integrity of the ranked matchmaking system by falsely inflating the skill level of the boosted person. This can lead to unfair matchups and negatively impact the experience of other players in the game.
Additionally, boosting is against the terms of service of most online games, including League of Legends. Players caught engaging in boosting may face penalties such as temporary or permanent bans on their accounts.
Therefore, it's important to avoid participating in or promoting boosting activities to maintain a fair and competitive gaming environment.
