Twitch is a 3rd party platform that is not owned by Frontier Developments. If you believe someone has breached Twitch's Terms of Service or Community Guidelines you should look to report the matter to Twitch directly.
You are able to submit some of the following via Twitch if it has occurred on their platform:
- Hateful Conduct and Harassment
- Unauthorised Sharing of Private Information
- Violence and Threats
- Other Terms of Service or Community Guidelines violations
The method to report a Twitch user can vary depending on which violation you are reporting, and where on the site it has taken place.
