I picked this up from Steve Sailer:
Youtube Blocks Its Most Popular Chess Expert for Saying Things Like "Black Threat" and "White Must Attack"
We hear much about the menace posed by racist robots, but mighty Google appears to have succeeded in inventing artificial intelligence with the natural stupidity of a professor of intersectionality.
Apparently the chess expert was unbanned after 24 hours.
The article that Sailer links to notes:
Experts suspect that it was the usage of words like “black” and “white” that confused the Yutube’s AI filters. They found that 80% of chess videos that were flagged for hate speech actually had terms like ‘black,’ ‘white,’ ‘attack’ and ‘threat.’
