Oh dear, it’s 2020 and the biggest and most AI-powered services on the planet are still relying on dumb keyword-blocking. AbeBooks reports that the pulp sci-fi double-bill paperback Mask of Chaos/The Star Virus has been classed by Amazon as a “medical device” and banned from sale.

Ironically, Amazon is still listing bat faeces sent from China, delivered to your door here in the UK. Apparently medical pseudo-science believes it to be a remedy for poor eyesight.
