The channel behind the shooting video is no longer accessible, and other streams have mostly reverted to memes.

We’ve asked Twitch for comment, although it stated on Twitter that it was “working with urgency” to remove the material and the associated accounts, many of which were “automated.” It also temporarily suspended streaming options for new accounts to minimize similar stunts.

While those measures should help, it’s notable that at least some of those streams persisted despite the likely violations. Twitch and other numerous live video sites have policies and tools to crack down on abuse, but they’re not necessarily equipped to deal with large-scale, near simultaneous abuses like this — they may need more aggressive monitoring to prevent future trolling campaigns.
