Scope is limited to old.reddit.com - this means it only works when the domain is *old.reddit.com/*

On the client, the add-on uses javascript to search through the dom for elements with a class name of 'promotedlink' and removes each element found.

source code below:
function removeElementsByClass(className){
var elements = document.getElementsByClassName(className);
while(elements.length > 0){
elements[0].parentNode.removeChild(elements[0]);
}
}

removeElementsByClass('promotedlink');

document.addEventListener("DOMContentLoaded", function(event){
removeElementsByClass('promotedlink');
});
