Try to query it though via document.querySelectorAll('a') for example. It's a good first line of defense as a lot of scraping techniques do this approach. However, if you have a headless browser setup for scraping, and simply fetch the current URL while on the page[0], you can get the plain text, and do a regex search for email addresses which will get you the email address - albeit this is a strange approach to take…
