>>8It does make you wonder why no one else has done this. I guess google does it for free at the expense of the user filling out a second word. But I'm surprised there isn't a foss captcha, or that if there is one why people use the google one that inconveniences their users with a second word instead of the (probably kind of shitty) foss one. It's not like it's hard to distort text. I guess the challenge is distorting it to the point where people can read it but the common bots still have difficulty.
