Do Banks use the Internet?

From a recent discussion, I wonder whether financial institutions acutally make use of the internet when rating customers.

Does my bank google for me when I apply for a loan/mortgage?

Or do they check Xing or LinkedIn to see how I am connected in my job? It might be possible to find indicators on how secure my job (in general) is, or how easy I find a new one, etc...

Does my insurance company check the internet? E.g. flickr to find out how much I'm travelling abroad?

Does anyone look at myspace or (more likely) facebook?

Do they learn from the information I give them anyway?
