The New York-based advocacy group Don’t Delete Art has launched a guide aimed at helping artists avoid censorship online, giving advice in areas such as self-censorship and pixilation along with details on “shadowbanning” (removal of banned hashtags linked to “borderline content”). The move comes after hundreds of artists complained that their appeals to social media giants, such as Facebook and Instagram, about removing their works were ignored. “This new guide combines advice from Facebook and Instagram staff, with insights from arts advocates and artists about how to comply with the vague, and often capriciously-applied, rules that govern what art is allowed on social media,” says a campaign statement.
