Captcha is something which was produced to stop automatized computer spam robots from meeting out forms, harvesting email addresses, as well as then sending out countless spam emails.
Some people and companies put those on their websites to make sure that the person filling out a form is actually human, and not a "bot" that will just submit a bunch of garbage or spam or try to fish for email addresses and such. The reason it uses highly distorted letters and numbers is that we humans are WAY better at recognizing them, even when they're all bent out of shape, than machines are. Even if a spam bot had optical character recognition (OCR) software, it would still find it nearly impossible to figure out what all those twisty, colourful shapes were, preventing it from giving the right answer to the captcha test, and keeping them out of the form's results. Hope that clears it up!
