Remove "Smart CAPTCHA" paragraph?[edit]

For the life of me, I can't figure out what this paragraph means:

Hi were rype more captcha Vijay241952 (talk) 13:25, 26 January 2017 (UTC)

Looks like somebody fixed it. --Guy Macon (talk) 18:36, 5 November 2017 (UTC)

Backronym?[edit]

The article currently claims that "CAPTCHA" is a backronym, meaning that the words were chosen to fit the existing name, but if that's true, it doesn't explain where the name came from. The source for that sentence only says that "CAPTCHA" is "short for" the given phrase, which would support it being a normal acronym.

Any further information? 2.25.149.9 (talk) 19:49, 29 May 2017 (UTC)

There is no rule saying that a backronym cannot also be a neologism. --Guy Macon (talk) 18:44, 5 November 2017 (UTC)

Visual Captcha[edit]

What about visual Captcha, where the human operator has to distinguish the shape? ("check all squares with cars"). Also, Stanisław Lem mentioned captcha in his books in the 1960s (! - a hint: it was employed in an elevator, with a chatbot). Zezen (talk) 06:35, 17 July 2017 (UTC)

Got a citation or a book name and page number for the Stanisław Lem claim? --Guy Macon (talk) 18:46, 5 November 2017 (UTC)
