The only line a terrorist couldn’t cross was personal harassment. You could tweet, generally, about how all “kuffar” (non-Muslims) deserved a violent death; you just couldn’t tell @hockeyfan123 that you were going to cut off his head. Although many voiced frustration that terrorists were allowed on the platform, Twitter brushed off their complaints. If the NATO coalition could tell its side of the story in Afghanistan, the thinking went, why not the Taliban?
