I once called an overseas number that was not saved on my contacts list. I was so shocked when a specific name came out on my phone with the name of the caller ID service provider! Take note, that was an overseas number and yet they knew the owner of the number. That is scary!

While it is good for us receivers to know who is calling, it is scary to think that those caller ID companies are able to know and broadcast you as owner of specific phone number. That is the reason why I am not a fan of services like this.
