Twitter is being criticised for failing to show any photos under the bisexual hashtag.
Some are calling it bi-erasure, as photo results for “lesbian” and “gay” still exist.
Users are pointing out that when you search #bisexual, a message appears on the photos tab stating: “The term you entered did not bring up any results.”
Kate Harrad, of campaign group The Bisexual Index, tells Newsbeat that bisexual people have “historically been hypersexualised and associated with porn and promiscuity”.
