btw if you want to remove these bits from the ACM digital library site you can use these uBlock rules

dl.acm.org##aside[data-core-aside="right-rail"]
dl.acm.org##div.edition-badge-wrapper
dl.acm.org##div.upgrade-banner

if you don't have premium, you can also use these to remove those "features"

dl.acm.org##section#sec-terms
dl.acm.org##section#sec-recommendations
dl.acm.org##section#sec-comments

unfortunately this leaves a big blank margin on the right side, but you can fix that with a userscript (which removes the sidebar ads anyway)

// ==UserScript==
// @name fix ACM DL
// @match https://dl.acm.org/*
// @grant none
// ==/UserScript==

(function() {
 'use strict';
 document.querySelector("article").removeAttribute("data-has")
})();
