Hi Doctor, thank you for making a player report! Unfortunately, I am unable to take any action for the following reasons:
No STEAMID
No evidence
While we can get this information from our logging system, it resets daily and I can not find the user at this time. If you see him on again, please call a staff member over or copy their id from one of the following ways:
The ID posted when they leave the server
Clicking on their name in chat and hitting copy id
typing: ulx copyid "name" in console
Have a good day!
