Dangerous GriGri belaying

This picture is a screenshot showing a dangerous way of clipping your GriGri into your harness. It turns the belay device 90 degrees meaning the risk of dropping the climber is increased. Later (minute 13), the belayer actually feeds out the rope by letting go of it. A Grigri blocked at the side in a combination with a relatively thin rope will make the rope just slide.*

Some 15 years ago, we saw several GriGri accidents due to this usage which was popular back then. I have personally told many of the biggest celebrities including a world champion that they instead should clip in the screw carabiner only in the belay loop of the harness. Some ten years ago I also had Petzl delete a video that had been shown like 100' times. I have made sure that the belayer in the video will be informed about the situation.

*It should be mentioned that also a Grigri which is turned 90 degrees normally blocks also thin ropes, as the Grigri normally turns into its correct position in a fall, especially if you stand some few meters from the wall.
