You know how some websites make you enter in a “security code” when you sign up? The code is usually some image file of numbers and letters and deters pattern-recognition software by slightly jumbling up the lines that form the letters/numbers. I guess the purpose is to prevent bots from hitting the site and spam registering.
The problem is that half the time, I can’t even make out what the letters and numbers are supposed to be. The lines are too squiggly that I can’t tell if something is supposed to be a “b” or a “6″, for example. So I enter in what I think the code is, and I’m told that my registration failed because I did not input the security code correctly. Grrr
I’ve had the worst luck with blogspot blogs that require logging in for commenting; those codes are the by far the toughest to decipher.
Yeah, next thing you know, they’ll integrate those color blind tests into the scribbled letters and numbers to make it even harder. :-)
