The notice may be worrying for some streamers who were affected by the waves of takedowns that hit last year, because if a user gets three copyright strikes on their channel, they will be permanently banned from the platform, according to Twitch’s policies. With this advance warning, it seems Twitch is trying to get ahead of a sudden flurry of takedowns and give streamers some time to remove potentially offending VODs.
