あなたはわたしの父について言われた。

[mike-lima]

English Translation

You referred to my father.

Why isn’t this “you were told about my father”?

No, the original Japanese sentence from Tanaka Corpus is grammatically unnatural. It doesn’t mean anything, seriously
The only possible interpretation I can deduct from the Japanese sentence is “You were complained/criticized about (mistakes made by) my father”, suggesting that you are a supervisor of my father and you are responsible for the inconvenience caused by my father.

“You referred to my father.” (you mentioned my father.) = あなたは私の父について言及した。（げんきゅうした）

“You were told about my father.” = あなたは私の父の話を聞かされた。or あなたは私の父について聞かされた。
