If I have a site that produces leads from good quality (probably mostly middle class) customers who are happy to share their data with this type of info:
-sex
-age
-homeowner y/n
-mortgage y/n
-life insurance y/n
-address
Presumably this info must be worth something to someone to resell given the money in life insurance etc
