Since the early days of the Overwatch League, Blizzard has had difficulty getting fans, and even pro players, to behave themselves in the Twitch chat. Whether it's spam or emotions that only post offensive messages, every week the Overwatch League means more restrictions. However, when we enter the second season of the league, Blizzard tries to fight the poisoning of Twitch chat through a new program that will be tested first during the Overwatch Contenders.
Contenders, the semi-professional division of Overwatch League, hosts its own broadcast on the Twitch channel which is separate from the pro Blizzard league. It's on this channel that Blizzard will run the first test of the new chat moderation system.
Viewers who want to participate in Twitch chat during the Overwatch Contenders stream need to link their Battle.net account with their Twitch account. The restriction, Blizzard hopes, will lead to "a more positive viewing experience."
While it's clear that Blizzard hopes that this new program will help clear the participants' chatter, and by extending the amateur and pro scene, it's not clear how exactly it will do it. The post itself does not mention possible penalties, such as restrictions on chat or ban, let alone the connection of penalties that may exist on the user's Battle.net account. While Blizzard hasn't announced specifically about moderation, it's possible that more information about the new program will be revealed after testing.
The new chat program will launch its first test during the quarter-finals of the Overwatch Contenders season which runs from December 28 to January 12, 2019.
