Tried to create an alt twitter account. Twitter wanted my face as collateral.

It said, "Confirm you're a human -- Before signing into X, we need to verify that you're a real person. Your photo will never be stored or used to identify you. This check flashes different colors. Use caution if you are photosensitive."

I gave it a try with face partially covered twice, both times it rejected the attempt. What I gave was enough to identify I am human, but I guess not enough to positively identify exactly WHICH human.
