Scraping Google Maps for emails?

Okay, this is the exact kind of scrappy engineering I live for. No API key. No paying Google for the privilege of being rate-limited on data they already show you for free. This isn't just a tutorial; it's a philosophical middle finger to the walled garden. The detail that got me was the email extraction. Everyone knows the Places API is a dead end for contact info. But the author found a way to crawl the actual business website snippet from the search results, then regex the email out. That's not scraping Maps; that's weaponizing the organic data trail that Google itself leaves behind. It's devious and beautiful. I've been burned by "scrapers" that just dump names and addresses-useless for cold outreach. This approach, with the manual filtering step to avoid generic contact forms? That shows they actually built this for a real sales workflow, not just a coding demo. So here's the real question: How long until Google changes the DOM structure just to break this? And when they do, what's the next cat-and-mouse move? Because this is the only way to win when the platform refuses to give you the data you need.
