I'm amazed FTers are surprised at this. Quite a few companies will research their wealthy, prominent or high value clients. It significantly enhances their ability to sell/service you.
If you have a dedicated relationship manager at a financial institution, I can guarantee they have conducted 'wealth screening.' I believe in the US due to a lack of serious privacy laws, software exists to conduct this. The company generally has your personal details already, but they generally research your family make up including spouse and children's names, what school and university you attended, company directorships, what charitable or arts organisations you donate to as well. If they can't get the information, they will pay a researcher to do it. I can speak on authority that charitable organisations also do this for their major donors. If they conduct this properly, you will never ever know that it has occurred.
I knew this practice existed with *wood because some Ws in South East Asia will put your Facebook profile photo in a frame ahead of your arrival. I know Qantas researchers First class pax to arm First hosts with similar intelligence.
Creepy when you find out, yes, but it's also a widely used business practice. See
