The fault of reCAPTCHA lies in the fact that it is used to digitize non-digital texts maybe to OCR the web, as well as stop spam. What this means is that in every captcha, there will be two words: One that the computer knows is right and will compare and check your text against and one that it hopes to use to digitize text. In other words, reCAPTCHA only needs one word of your captcha to be correct for your captcha to be accepted.
You will be given two words: [Real, Fake] or [Fake, Real]. The fake word is unknown to the computer and can be replaced with anything.
Let me show you few examples of how ALWAYS FAKE words look like:
Words with accents or punctuation:
Almost always fake:
Words with the following are usually fake with few exceptions. Sometimes you will get surprises, however.
Odd or non-matching fonts:
Deformation caused by scanning:
Things to remember:
1. The fake word is usually the one which is blurrier and harder to read, even if by a little. However, sometimes it is the one which is unusually clean and easy to read though the quality of the scanned words varies greatly.
2. Real words usually use the same type of font throughout as they are computer generated, while the appearance and font for fake words can vary greatly as they are scanned from multiple sources. See the “Odd or non-matching fonts” above for examples.
3. The fake word is usually thicker, bolder, and blacker. But sometimes it is also thin and long.
4. A fake word’s alignment of letters are more likely to be in a straighter line or a smoother curve as it is scanned from a printed material. A real word’s alignment of letters are more likely to be wavy and a bit jumbled up due to being distorted by a computer.
5. You’ll sometimes get words with lots of noticeable dots around them. They are obviously scanned from books and therefore, fake.
6. Practice! Once you start out, You’ll have difficulty identifying which captcha is real, But after doing a few dozen, You’ll be proficient in picking out fakes and this will be such a great time saver for you.
Update: I’ve been seeing a lot of comments like… “Yeah, How noble! screwing over a worth project. What a time saver!”
Guys, I’m not asking you to do that everytime you see a recaptcha. If you do have the time to read indecipherable text and fill it in then great, Thank you. But think about if you’re probably late for something and you have to download a file or leave a comment before you go, Will you keep refreshing the recaptcha until you find a word that you can read?
You get my point.
