i encountered this for the first time today while attempting to read something on archive.today.

i confirmed that decoding the qrcode using a computer and following the URL it contains is insufficient; the error it gave directed me here which is what the linked screenshot is of.

the old type of captcha remains available too, for now:

    Since a QR code is just made of squares, it can be very, very tiny

    1 square = 1 pixel
