Honest question. I’m vaguely familiar with streaming software and fairly tech literate.
How does something like this accidentally happen?
Also, OP says he forgot to turn off the camera and masturbated but that doesn’t seem to be what the video depicts?
The video source got switched to a, frankly, suspiciously fast placed montage of hardcore gay porn. That’s not the same as leaving the stream on a blank video feed with occasional clicks.
