It does seem, from a maximum-paranoia standpoint, like this confirms the current status of your information, adds any pieces they were missing, and provides an indication that your data is extra valuable.

After all, you're tech literate (suggesting income) and privacy aware (suggesting your information may be scarce)!

(I assume most of these groups are more honest than that, if only because data reselling is legal but that wouldn't be.)
