ListSource mining BP profiles?

[Andy H.]

We recently got an (unsolicited) email from a wholesaler in our area saying he got our email address from a list of cash buyer investors that he purchased and asking if we wanted to stay on his buyers list. To the best of our knowledge, we had never met him before, and the email address he contacted us through is not one that we have given out much. It is listed in our BP profile though. 

We weren't necessarily opposed to being on his buyer's list since we are looking for deals in the area, but were curious how he got our email address. So, we asked him, and he said it was on a list of cash buyers that he bought from ListSource.

Not sure how we ended up on one of their lists, so we're wondering if maybe they are mining BP profiles.

Anyone else had a similar experience?
