Your home address could be floating around somewhere on the internet in more places than you'd expect. I googled my own name recently and was genuinely shocked to see where I currently reside and even the previous town I lived in pop up in search results.
Between data brokers selling information, old account signups you've forgotten about, and social media profiles you filled out years ago, your address gets shared, indexed, and distributed without you really noticing. While you can't scrub your address from every single corner of the internet, you can make it significantly harder to access.
