Last December, 2018, facebook started spamming my feed with an upcoming show of John Maus at the Great American Music Hall, which I promptly ignored. I mean, come on, I'm not dumb enough to fall for clicking like on sponsored posts or reposting them or even turning them off cause I don't want to give FB any kind of data on what I do and don't like. Never heard of John Maus, not interested.
But here's the thing. They don't need any more data about me. They already got me figured! I mean, for the most part. I still get ads for terrible kickstarters cause I backed one one time and they think I'm really interested in Neil Gaiman (I am not). But anyhow, I finally came across John Maus and yeah, they got me figured out at least that far. Still, not about to interact with any sponsored ads.
