Captcha. 0 and O.
I visited Habr today and collided with a captcha, where an oval was drawn for recognition.
Is it really not obvious that O and 0 in most cases look the same? (I especially liked that all characters except zero were letters).
With a similar situation met not only on Habré, on other sites often had to choose, for example, the capital letter or uppercase (guessed not always).
Is it so difficult in the captcha to avoid thesame similar characters?
