captchas and racism

From #drupal:
arnab: and the fact that captchas are, well, stupid
chx: yes, visual captchas are stupid
chx: I think the textual ones are better
chx: if you REALLY want some captcha then something textual
UnConeD: Welcome to my site! To register, please answer the following captcha!
UnConeD: What is the 312455th digit of Pi, in base 42?
chx: UnConeD: LOL
arnab: heh
arnab: exactly my point.
chx: rather “what is the eleventh letter in this sentence?”
UnConeD: well
UnConeD: that sort of stuff is easily cracked with regexps
UnConeD: some guy once made a math expression captcha in text form
UnConeD: in a patch to the module
chx: yes yes
UnConeD: i followed up the issue with a PHP script to break his code ;)
chx: I liked that one
chx: Well I think I can rather easily make a textual captcha you won’t be able to script
arnab: chx: make one, I’ll crack it :D
UnConeD: you are no match for my dangerous RegExping skills
***UnConeD casts Capturing Parentheses (opponent’s movement reduced by 50%)
chx: UnConeD: beware, I’ll grep the CIA World Facts book and ask questions based on that and you can eat your regexps.
UnConeD: err
UnConeD: but grep is itself regexp based :P
chx: I mean, I’ll compile a huge list of facts based on World Facts wikipedia whatever
arnab: chx: I have an indexed, parsed dump of Wikipedia on my HDD, will break your CIA thingy in 2 minutes with it
chx: and questions like “Is Ghana in Africa?”
UnConeD: i’ll hire an indian fellow with an encyclopedia
arnab: UnConeD: I AM an Indian fellow with an encyclopedia
arnab: rofl
UnConeD: ;)
