There is an annoying spammer of cheat software in the chat room that has his name NOT showing up so you can not even mute that account, not even mentioning being able to report it using steam report system. There is just no way to look up the account that's doing it.

Please can some admin elevate it and maybe find and ban that account... hopefully something can be done also about not being able to click on the messenger name and report it.

I could not upload an image to attach it to this post so please see it on my dota content location here https://steamcommunity.com/sharedfil...?id=1637869062

OK I found that if he posts while I am not in a game I can catch his account in a chat user list because what he does is join a room post a spam message and leave within 10ish seconds
