For several months, one of the people running in the primary for the open seat in the US Senate for California has been sending me emails about our "shared Jewish values".

This started quite early on my journey towards joining the tribe. I certainly did not tell the American Democratic Party that I was considering becoming Jewish.

I wrote to the campaign and asked for the source of their information (and their position on data privacy) and received no reply.

I had recently started following a bunch of twitter accounts like @jewwhohasitall and several other Jewish accounts, so I do think Twitter was the mostly likely source of this metadata, which they sold and which either included my voting state or was compared to other data to uncover this.

Which means, essentially, that Elon Musk has a list of Anglophone Jews and roughly where they live.
