Imagine transcription: An image of Light Yagami, Misa Amane, and L from Death Note on a fiery background. The caption reads: "Did you know, in the anime 'Death Note' for copyright reasons, the milk has to be spelt 'MLK' on the cartons? Google 'MLK Death Note' to find out more!". End transcription.
It's reasonably safe to Google, it's about this letter where the FBI encourage Martin Luther King Jr. to commit suicide, using particularly abusive, dehumanising and degrading language. The content of the letter isn't necessarily hard to read the if you want to read it, particularly as it didn't work, but it's still bad to know that this was an official government plot.
