Sorry your report is being answered a little late. Firstly, I realize your mid-game (nice job surviving btw) so it can be a bit difficult, but if you could get even a screenshot of status at some point it would help a lot in identifying the right players.
Reported player syrps is banned for 1 day
Other player in the demo, mike, is banned for 1 day also
The command "status" in console. Just for the player "mike" as an example, sure I can eventually go and find the right player because I have access to the right logs, but for a normal admin it would be difficult/impossible to find the correct player named "mike". So if you took a screenshot of the status in console after finishing your demo, the admin responding to your request could see the correct ID for that player without having to search for it. Basically just saves a bit of time, or in a case like this where someone has a common name, makes it possible for an admin without log access to punish the right player(s)
