Earlier today League of Legends team has released a statement on investigating the cases and banning 16 people from competing in the Oceanic Challenger Series league. That amounts to 40% of the participants.
The severity of the punishment relies on the violations. Those include negative behaviour, account sharing and account boosting. The latter means players “piloting” other accounts to increase their ranks.
League of Legends Challenger Series will continue on schedule
Riot is currently working with the affected teams to make sure they still can compete in the Challenger Series as the ban happened 2 days before the season’s start.
