I’m from a culture in which family use a very small number of very highly conserved names and non standard name positions. I’ve noticed this is sufficient to confuse the low rent data brokers that do statistical linkage. My parents and grandparents and my siblings and my children have all at various points shared addresses landlines and have overlapping names. The brokers are very unclear on how many people are involved , what sex , what generations what states.

I grew up around some people with the last name "Null". I often wonder how they're doing for data privacy today.
