Meta is most certainly addicted to bad data.

I believe this because Facebook continues to send spam to an e-mail address that was only used by me for my cat, and only once; and the cat has been dead for 15 years. The dead cat address received three spams from Facebook just yesterday.

There is also bad data out there about another cat that died ten years ago. He keeps getting snail mail from political candidates trying to convince him that they're deeply interested in the cares and concerns of people like him. A dead cat.
