Then Self Delete or get rid of the source. You aren't affected by events for the first few seconds after you spawn, so it should be possible to avoid it. If someone is playing annoying sounds at you, they could just as easily be setPlayerTransform trapping you in a wall, instantly killing you or doing other things. If you cannot avoid it on spawning, leave the minigame or server.
Most events can be abused in some way, but they also give people options for more interactive events or builds. I found a need for these events a while back in making a puzzle, where I needed to play a sound to the client who 'picked up' an event-based tool needed to solve it, so I made this and released it to give other people the same option.
