I didn’t have a Twitter account but I needed one for a day.

Creating a Twitter account requires the solving of five “prove I’m not a robot” puzzles. They are not easy. There are two images from different perspectives and - non-intuitively - you need to click on arrows to move a person icon in one image to the same place it is on the other image.

The images have slightly different perspectives. It’s not always obvious what the arrow buttons will do.

I got the fourth (of five) wrong. Did I have to do it again? No, it took me back to the beginning: five more to do.

If Elon doesn’t want Twitter users, he could just say.
