Adguard's custom adblocking rules for rel=nofollow (using Monolith as an example)This paper discusses how to use Adguard's custom rules to block advertisements on Monolithic websites, proposing to do so by using the fixed attribute rel value of the a tag in the advertisement as nofollow. Since the DOM elements of advertisements are difficult to locate accurately and conventional blocking methods are ineffective, it is proposed to use specific rules to hide these advertisement links. Specific examples of blocking rules are eventually provided, and URL blocking is noted as a more general solution.
