Twitch, the livestreaming site owned by Amazon, are trying to sue the digivandals who in May broadcast videos of pornography, copyrighted movies and TV shows, and actual real-world murders. The offenders pretended to be streaming Artifact, dominating Twitch’s section for the Valve card game. Twitch don’t yet know who they are but have already filed a lawsuit with a California court to get it rolling. When they do know, they’ll look to hit the perpetrators with fines and bans for cyberoffences from trademark infringement to fraud.
