I once happened across a Github where all the repos were subtle little bits of anti-Semitic cant relating to the Holocaust. More than subverting them, they also often function as dog-whistles for fellow travelers.

(For those not getting the specific one used above, Lovecraft had a black cat and a common name for black cats at the time combined a now nigh-unprintable racial slur for black people with the word 'man'.)

Github has a reporting feature!

There’s an NFT collection called Milady which has subtle Holocaust references - ‘Treblinka’ written on shirts, the rarest traits are ‘SS’ tier etc.
