What’s the difference between “delisting” and “removing at source”?

"Delisting" refers to removing a link from search engine results (Google, Bing), making it harder for users to find the infringing content organically. "Removing at source" involves directly sending a DMCA takedown request to the platform or website hosting the unauthorized content, aiming to get the actual content removed. While delisting is generally quicker and more straightforward, removing at source is more comprehensive but can be more challenging due to various factors affecting its success.
