"Isis supporters have threatened Twitter employees... with death over the social network�s practice of blocking accounts associated with the group."

"In an Arabic post uploaded to the image-sharing site JustPaste.it, the group told Twitter that 'your virtual war on us will cause a real war on you.' It warned that [Twitter co-founder] Jack Dorsey and Twitter employees have 'become a target for the soldiers of the Caliphate and supporters scattered among your midst!'"

�You started this failed war � We told you from the beginning it�s not your war, but you didn�t get it and kept closing our accounts on Twitter, but we always come back. But when our lions come and take your breath, you will never come back to life.�
