A bot would miss a few by guessing, but it'd frustrate the grammatically challenged. They all watch too much MSNBC... they get ideas. |

They need to make a version of that pick the cats captcha that doesn't require JavaScript. Outside of that issue, as a real captcha, I see it working. --- |

Steam has (had?) notoriously difficult captchas (I don't think the service itself, but the forums and such).

Keeping educated people from accessing a tremendous source of education seems a touch counter-productive ... -- |

CAPTCHAs work well for stopping bots (although a simple Q&A may work better), but they do nothing to stop SEO spammers. For example, of the last 100 a.cc registrations, 83 have been spammers manually registering via the help of form filling software, etc. |

Speaking of SEO spammers, one (Basementalice) posted a profile page on the wiki. -- |

You should not accept any join_dt that is less than a week. All spammers active or not will be deleted by that time. |

Maybe I'll add that grammar captcha append: Actually, I think I can let them log in, but make their account a "Guest" or "Read only" account for a week. Maybe. Still don't like restricting valid users. -- |

These are real people, so a CAPTCHA won't help. Even a 24 hour limit would probably be sufficient. (Time is in UTC.) It's just that there are some people who make an account, do nothing, and come back a few days later to insert spam. But those people probably aren't the ones likely to try the wiki. |

Who said anything about spam? This captcha is about stopping people that don't care about spelling or grammar from accessing the Internet. -- acc.js | al4anim - Allegro 4 Animation library | Allegro 5 VS/NuGet Guide | Allegro.cc Mockup | Allegro.cc <code> Tag | Allegro 4 Timer Example (w/ Semaphores) | Allegro 5 "Winpkg" (MSVC readme) | Bambot | Blog | C++ STL Container Flowchart | Castopulence Software | Check Return Values | Derail? | Is This A Discussion?

Myrdos said: How do you separate the spammers from valid users? The patterns are obvious. The easiest-to-detect log in from an IP in India, Singapore, or the Philippines but claim they are from the USA. Then they post bbcode into their profile and leave. Those could easily be instant-banned with 100% accuracy. To get around that, they try to create a silent account and insert the spam later. But then they find out that their accounts are being deleted automatically for lack of activity. To get around that, they post a seemingly on-topic reply to any forum topic. But that is a sure sign of a spammer too as nobody (especially on this forum) joins out of nowhere just to reply to a topic. So the only thing they could do to avoid detection is to actually actively participate in the community as a regular programmer would. But then once they try to insert a spam link somewhere they'd be banned anyway. |

Although it's not that likely that someone would just join to reply to some random topic, it's not impossible either.

The likelihood that the person is a spammer is nearly 100% given that he never visited the site before and came from an external application. Most people come here from a specific programming related Google search and don't join until lurking around for a few weeks. When you take that with a fake sounding name and/or a spammy business email address, it's 100% sure it's somebody who is up to no good. |

So, what I'm getting from this thread, is that it's still too early for me to start my spamming plans.

Breed bots with perfect English grammar.
I think a grammar based captcha system is a good idea, but it needs to be more complicated than that so that it can actually have thousands or millions of possible captchas. You'd need to require somebody to fill in a few blanks, including properly capitalization and punctuation. It would need to be able to accommodate the occasional screw up by a human too.
