I think this is a hoax. Tried around 100k compressed/uncompressed legacy addresses over night, zero history or balance on any of them. There are around 7000 files in each ISO. Didn't bother to undupe the hashes, some files didn't change.
Only tried english ISOs though. XP Pro/Home original OEM, all SPs, retail / VL.
At this point it's not worth my time anymore, so good luck to everyone else.
