Sexually explicit webcam material proved to be a particular problem for GCHQ, as one document delicately put it: “Unfortunately … it would appear that a surprising number of people use webcam conversations to show intimate parts of their body to the other person. Also, the fact that the Yahoo software allows more than one person to view a webcam stream without necessarily sending a reciprocal stream means that it appears sometimes to be used for broadcasting pornography.”

Bold by me.

So GCHQ uploaded bulk chatterbate pitures?
