That is a possibility. Another scenario is one in which you sign up to a service like Optery and submit a non-existent individual with fabricated information for PII removal; after about a month or so, this fabricated individual started showing up as a possible person that lived at my address when I was trying to get a quote from Progressive.
So, seems like somewhere in the midst of this process, one of the 240 brokers that Optery sends your information to get it removed, someone aggregated it, sold it to Progressive and in the underground realm of data brokers and buying and selling data, someone unfortunately (or fortunately?) is now targeting 'Paige Notfound' and 'Meg A. Byte'.
I got the last laugh! :)
