Viewers can send confetti whenever they want and as frequently as they want. As a viewer sending confetti this will only display over the player for the sender, this is not rendered in the visualization URL. A confetti explosion will be rendered to the visualization URL once a certain amount of confetti has been saved up and the process starts all over. Explosions should be limited to once per minute. As a broadcaster you can simply hide the browser source containing the visualization URL to hide confetti / click map if you want to disable it.
