Evidence of SteamID - something you removed from the template in your post - is also necessary for this to be handled. If you did have proof we'd only be able to see a name. We'd have no way to know if that name belongs to the SteamID you have added in the report.
Next time type
status in chat. This will give you a list of all users on the server and their SteamID. Then screenshot that.
Anyways, as you have no proof, do you want me to lock this? We appreciate the effort you put in regardless, it's a super nice thing of you to do
