Iirc these were often used to train algorithms to read scanned text. Give one scanned word, and a generated gibberish word. If the gibberish one matches, weight the scanned word closer towards understood. Check consensus on that scanned word for a bunch of users, and you’ve now confirmed the scanned word is “arch.”
Sometimes I miss the old Captchas.
