On June 28, 2020, while presenting a chess podcast on Grandmaster Hikaru Nakamura, Antonio Radić's YouTube handle got blocked because it contained "harmful and dangerous" content.

In this paper, via a substantial corpus of 681,995 comments, on 8,818 YouTube videos hosted by five highly popular chess-focused YouTube channels, we ask the following research question: how robust are off-the-shelf hate-speech classifiers to out-of-domain adversarial examples?

We conclude with an intriguing analogy result on racial bias with our findings pointing out to the broader challenge of color polysemy.
