This hits close to home for me. I donated once to a friend’s campaign for local office and my personal (Gmail) email (which I don’t share with organizations I donate to) ended up on the Democratic Party mailing list and now I get daily spam with clickbait and outrage-inciting subject lines from every party-registered office holder in the country. You can unsubscribe to as many as you want, every day there’s a new PAC targeting you with their spam.
