At the beginning of 2016, Twitter announced some good news: the formation of the Trust and Safety Council, made up of more than 40 outside groups and experts tapped for advice “to ensure that people feel safe expressing themselves on Twitter.” By that point, the company had already spent years knee-deep in accusations that its social network was rife with abuse and harassment. Something had to change.

For the first two years of its existence, the council’s relationship with Twitter was relatively fruitful. Representatives met CEO Jack Dorsey at annual summits, and held regular calls with other company executives to discuss new policies well in advance of their rollouts. But this year, some council members say, Twitter has been far less communicative, leaving them to wonder whether its leaders still value their input and expertise.
