And then one day then decided to publish the one I'd given them for an identity check... in search results. I don't yet know why.
Since it was published by you as public contact information for your business on Google, either a customer or one of the contractors Google employs to update phone numbers in Maps listings then added it to Maps.
My post was about the Business Profile one. Which started (seemingly randomly) containing the same phone number.
Honestly, this policy seems absolutely backwards to me. I'm fine for customers to contact me via e-mail or my website, but why do Google get to suddenly mandate that I need to provide 24/7 global phone support to anyone (who doesn't even need to me my customer)?
But none of them (except the Google Play one, which I'm fixing) are associated with the business or were provided for the purpose of sharing when people search for a business that I happen to be involved with!
(I'm sure you wouldn't want your phone number to turn up every time anybody searched for your employer, even if you were happy for your phone number to appear on your personal website, right?)
I'm not claiming that my personal phone number shouldn't be online anywhere. There are plenty of places it's pretty easy to find!
I'm just saying that I didn't put my personal phone number onto a public Business Profile (only providing it for identity verification, many years ago). But then, randomly, one day Google decided to start publishing it to anybody who searched for that company name.
