Some info, yes. Definitely conclusive? I don't think so. It can be ie in form of my name & passport number. Which after changing the passport can suddenly point to number of persons from my area.

Even if it includes my address (which I highly doubt), it will be different than it was 10 years ago.

Eventually, they'll get there. But I am fairly certain today they are not there and they don't bother for average Joe anyway. For me personally, the experience, especially in hindsight for what it offered, was/is well worth this minimal risk.
