"We didn't have the capability to boot players from matches, so we had little recourse if a random player joined the server we had planned to scrimmage in. Most times those players didn't have a mic and rarely responded to direct messages, so we did whatever we could to urge them to leave. This included trapping them in the spawn with five Demoman, and setting elaborate traps with sentry guns in the most bizarre hiding spots on the map."
that is dedication
