| Oct 26, 2010 at 22:03 | comment | added | seanalltogether | I would argue that making this <noscript> compatible is a pointless requirement. The amount of people disabling javascript is negligible and those that do know how to enable it for the sites that need it. | |

| Oct 25, 2010 at 8:30 | comment | added | Tobbe | I vote for the trivia captchas. The main problem people seem to have with them is that they're hard to solve for someone who doesn't speak English. But I have to say: "Isn't that a good thing?". Do we want people who don't understand English posting questions on StackOverflow? | |
| Aug 7, 2010 at 8:01 | comment | added | Stefan Steiger | result = eval("7 minus 3 times 2".toLower().replace("minus", "-").replace("times","*")). Don't get my wrong, but how is that supposed to stop a bot ? | |

| May 5, 2010 at 15:59 | comment | added | Arlen Beiler | 7 minus 3 times 2 IS 1. You are supposed to do times and divide first. So (7-3*2) is calculated as (7-(3*2)). Remember your Algebra. | |
| Apr 21, 2010 at 10:35 | comment | added | Delameko | What I want to see is the CAPTCHA equivilent of those old 90s computer game copy protection schemes. "Go to google, search for 'foobar', what is the first word of the third result listing?" :) | |
| Apr 21, 2010 at 10:17 | comment | added | Petr Peller | @Brian To send the image, you have to create it first. Yes, you can keep it in memory and after sending throw it away ... this would kill the performance. | |

| Apr 19, 2010 at 16:30 | comment | added | phkahler | IMHO "7 minus 3, times 2" = 8. Without the comma, it's hard to guess the intent without hearing it spoken. | |
| Apr 16, 2010 at 23:27 | comment | added | Bill K | I think @Sosh is correct. Algebraic order probably only applies to equations in algebraic notation. | |
| Mar 30, 2010 at 11:11 | comment | added | UpTheCreek | @mwarenr: Sure, but when writen with words "7 minus 3 times 2" my first instinct would be to calculate it sequentially. | |

| Mar 4, 2010 at 1:28 | comment | added | Michael Warner | As anyone who studied basic arithmetic knows, multiplication is higher than subtraction in the order of operations, so 7 - 3 * 2 = 1; with or without parentheses. Are you smarter than a fifth grader? :) | |

| Jan 28, 2010 at 0:14 | comment | added | Bloodyaugust | Its one. Remember PEMDAS? OOP here people, OOP. Could also read like this... 7-(3*2), giving a value of 13. Definitely not the way to go... | |
| Jan 14, 2010 at 22:55 | comment | added | Mike Robinson | According to Wolfram Alpha, "what is 7 minus 3 times 2" is 1. I thought it was 8. I think you just invented the anti-captcha. | |
| Jan 9, 2010 at 3:44 | comment | added | Gabriele Petrioli | so .. what is 7 minus 3 times 2 = ( 1 or 8 ) ? | |

| Aug 27, 2009 at 12:16 | comment | added | meandmycode | I would imagine these kind of defences will be easily bypassed by scripts that just defer submitting the page for 30 seconds.. theres no initial cost in terms of its throughput only that when it first starts loading urls to spam, it has to wait 30 seconds before it starts submitting.. whilst this works today I imagine this will be easily bypassable. | |

| Jan 26, 2009 at 9:29 | comment | added | Adam Matan | Trivia questions are prone to cultural bias (think of a french guy answering your question...). Furthermore, they can tackle users whose English isn't native. Also, they can easily be broken using brute force (you only have ~2^#_OfQuestions options). | |
