The question about all of that? The accuracy.
I've searched my name and found a genealogy site indicating that I might be dead.
Most of the online ones show the last address I lived at before going to Japan (1998).
There are 1 or 2 that show my address as my father’s when he passed away (I have never even heard of/seen that one).
Thankfully, I have not been able to find any with my current address (I check monthly).
