When people started calling my personal mobile number with questions about a voluntary organisation I'm involved with, I was confused: we weren't sharing that number. It turns out that Google had decided to take the number I used to verify my identity for Google Business some years prior and start putting it in Google Search results. WTF, Google?
If it’s your personal info, you can ask for it here.
If it’s your own website you want delisted, that’s here.
Now do the same for bing, ddg, startpage, yandex, yahoo, kagi, brave, ask, ecosia etc etc…
Which is to say, if it’s on the internet and publicly accessible, assume it’s permanent and going to be indexed at some point.
