Guillermo Herbst	Sunday 09 December 2007 5:49:57 am Soy nuevo aquí y además tampoco hablo ingles por lo tanto me cuesta encontrar las extensiones, si existe espero me digan cual es ( me ayuda http://www.google.com/translate). La comunidad de Drupal encontró una solución simple para el Spam y como ya está en Ingles es mejor que leerla de ahí. http://drupal.org/project/gotcha
Piotrek Karaś	Sunday 09 December 2007 10:31:17 am Interesting idea, but I would be little skeptic about it: 1) If bots are able to learn how to read CAPTCHA, then why shouldn't they be able to figure out probable human visibility of a given HTML element based on given CSS? They can be taught not to fill in anything that a human being would not be able to. 2) This solution is of little elegance, to say the least. Lots of additional elements, code... 3) Wouldn't google possibly consider it "hidden content" in their spam report forms? I like the idea that you can actually distinguish and collect/filter spam requests, though.

Xavier Dutoit	Monday 10 December 2007 3:26:56 am I've tried a different option: instead of having the user typing the text read in the capcha, a js is executed and write it instead. So far, none of the spam bots I've seen have a js interpreter and it works fine, but I'm afraid that will change one day or another. X+ http://www.sydesy.com
Piotrek Karaś	Monday 10 December 2007 4:12:25 am I've also tried Flash for CAPTCHA purposes (http://www.ranking.slupsk.pl/index.php5/rankingi/15). That requires an intelligent HTML-flash variable passing method, it has to be encrypted or organized in a particular way. Unfortunately, some browsers had problems to display ActionScript-driven dynamic SWF files, and I haven't developed another working version, yet. SWF files can also be decompiled, so it's not unbeatable, either. -- Company: mediaSELF Sp. z o.o., http://www.mediaself.pl eZ references: http://ez.no/partners/worldwide_partners/mediaself eZ certified developer: http://ez.no/certification/verify/272585 eZ blog: http://ez.ryba.eu
Fabricio Guerrero	Wednesday 12 December 2007 2:30:43 am Hi Xavier, Do you have a viewable example of how your js works? Sounds very interesting. http://www.solobromasychistes.com <<Joomla Site :P http://www.recipesforhealthyfood.com/ <<Drupal Site :P http://www.ezforge.com/ <<future ezCommunity, Articles, forums and more...
