CAPTCHA would not be so bad if it weren't for Gray areas which may or may not go against your choice.
For exampe: Edge of a Sign (before you get to border) is not meant to be Picked even though instructions say to pick every square that has Sign(s).
Worst CAPTCHA I have ever seen was one you had to pick the narrow punched steel post the Sign(s) were mounted on. (Another website, where CAPTCHAs would frequently repeat.)
the reason for Captcha is to prevent spam bots and stuff like that. and they are getting more and more sophisticated at recognizing things..
so captcha has to get more ridiculous, the problem is a occasionally it doesn't just stop at ridiculous and goes full retard instead... and goes from making some sense into making absolutely no sense and becoming impossible because whatever trained the system must be cross eyed or blind or something..
image recognition derps:
signs are legit the worst, its 50/50 chance you need to include fringes and posts its attached to.
store fronts tend to be second worst in my experience, whoever trained it on store fronts isn't the brightest bulb availble, let's put it that way. there is occasionally times where it just fails you even if you nailed it..
and anything large tend to be poorly identified too, such as bridges, traffic lights, macro shots consuming entire grid, etc etc.
AlphaNumeric i also hate.. because always rotating or filled with junk to the point where i can't tell if its O, 0 or Q for example..
the most effective bot traps tend to be contextual questions that require humans... like "enter your age minus 1 year:" or "select the drones registered to your account" "verify your location" "enter your last name". etc etc. and based on what you put into profile already it will know the answer behind the scenes, very simple system. also contextual questions based on information in your profile help limit/block hijacked accounts because usually they wont know the answer.. |
