Images of Jesus and superheroes caught up in Tumblr porn ban

Ballet dancers also flagged up as explicit content under blogging website's new rules

Ballet dancers, superheroes and a picture of Christ have all fallen foul of Tumblr's new pornography ban, after the images were flagged up as explicit content by the blogging site's artificial intelligence (AI) tools.

The company, which is owned by the US media conglomerate Verizon, said on Monday it would ban pornography from its site - and defined the term as covering any depiction of "real-life human genitals", or "female-presenting nipples".
