Reddit's one is crazy, I didn't know it exists until I was researching some tax laws in my country. I saw a Reddit thread in my language and it took me a while to realize it's a US-centric subreddit just automatically translated. Translating content about US laws makes 0 sense!
I mean, there are people living in the US, who are subject to the taxation there that don’t speak English.
As someone who also lives in a country where I don’t speak the language (and certainly not well enough to understand tax law); having that content translated is potentially useful IFF it’s clearly labeled as such.
