Summary: Three professors, Tama Leaver, Tim Highfield and Crystal Abidin, wrote a book about culture on Instagram and how it developed. The book, entitled Instagram: Visual Social Media Cultures, was released in February of 2020. Along with the book, the authors set up social media accounts to both promote the book and to continue the discussion about how Instagram culture has developed. Not surprisingly, one of the social media accounts they set up was on Instagram itself.

On Instagram, the account would post images about Instagram (including examples of its content moderation issues). The authors were surprised in mid-September when Instagram shut down their account without any clear reason.
