Some users on twitch unfortunately harass and target minority groups that being members of lgbtqia+ and PoC. If users are repetitively banned in say like 20-30 lgbtqia+ or PoC (tagged as such, like mixed race, african American;etc.) streamers channels, their accounts should be suspended then possibly sitewide banned, if there is a repeat offense post suspension.

There should data that collates this info and action as a result based of this also.

Being a streamer who fits into both these categories sometimes it gets a bit much having to ban and then also report these users, half the time i don't bother with the report.

An auto feature that can track harassment will be great, this will also fast disable burner accounts made to harass people.

Having a system where people can appeal to twitch also when banned, will fix any issues in this system.
