League of Legends players were not able to monetize their Twitch streams until now. In recent news, Riot Games confirmed that players are no longer banned from receiving Twitch subscriptions and donations. However, players are still now allowed to have sponsors or paid advertisements.
Riot Games has offered a further explanation of the changes to donation restrictions for its casters. The company confirmed that it worked with individual casters to determine their passions and interests, and contracts were updated accordingly as a result. It is not a blanket policy change.
