I am certain that we have all reported a user on Twitch before, as I have since making my account in early 2017. However, recently, after reporting a user, I received an email saying "We've actioned on your report" in regards to a report that I submitted previously.

There was very little present in that email. It simply told me that my safety report was reviewed and staff determined that a violation of the Terms of Service and Community Guidelines had occurred, and proper enforcement action has been taken. That is it. That is all that was included in the email. For an email that is supposed to update you on what happened after a report in regards to a very serious issue, there was very little to get out of that email. A lot of the things that, in my opinion, should have been included in that were simply absent. Here is what I would like to change about it:

Include the original report(s)
This would serve two very important purposes: it will tell you the user who you reported and what they were reported for. As someone who has reported a lot of accounts, especially this year when I have had a lot more time to stream on Twitch, it is difficult for me to know who the user I reported was. Including the original report would allow me to see exactly what user I reported. Including the original report would also remind me of what all I reported the user for and what evidence I presented or was available at the time, which is relevant to a safety report such as the one I submitted. The exact details I reported are not relevant to these suggestions, but understand that the situation I reported has extended to platforms beyond Twitch even after the report. Including the report(s) that were considered would address both of these problems.

Describe the enforcement action taken
Safety reports or reports concerning Community Guidelines or Terms of Service violations may involve things such as abuse, threats or acts of harassment, bullying, and many more things in which someone may experience long-term harm. Again, while I do not believe the details of my report are relevant, the things that I reported have the potential to cause long-lasting damage for the people affected. In the case of a reported abuser, it will most definitely bring comfort to the victims knowing that the abuser will have their account terminated and will no longer be able to create additional accounts. It does not have to be anything complex, it can be something as simple as "The account of the user who you have reported has been terminated and indefinitely suspended from the use of our services." As long as it lets the person who submitted know that something more than just a warning or a suspension had occurred.

Whether or not both of these changes are enacted, more should be included in an email describing that action was taken following a user report.
