Streaming Platform Announces Significant Expansion of Misconduct Policy
From here in more detail
Now the service policy is divided into two parts:violations committed on and off the site (this part remained unchanged) and violations committed only outside the site. This means that if, for example, the administration is considering a complaint about harassment on a stream, then user behavior, for example, on Facebook, will also be taken into account. Twitch will use third-party law firms to investigate such cases.
Administration comment
"Such investigations are much more complex [than internal investigations] and also requiremore resources and time," the company writes in a blog post, "For all the breaches that occurOff-site, we will use the law and the help of third-party services to obtain reliable evidence before making a decision."
