Thanks for posting, next time keep in mind:
- Name your demo something descriptive, like "playername_speedcheat.dm2", instead of "hax.dm2" or "cheater.dm2"
- Report the time that the demo was recorded
- While recording, type "players" at the console. If you're an admin, type "listuserip" as well.
Also in demo is name is BOOMCHACALAKA not BOOMCHAKALACA
