Once again: captchas have zero security value. They either defend (a) resources worth attacking or (b) resources not worth attacking. If it's (a) then they can and will be defeated as soon as someone chooses to trouble themselves to do so. If it's (b) then they're not worth the effort to deploy. See, for example:
CAPTCHAS are a "defense in depth" that reduce the number of spam incidents to a number manageable by humans. Not all bot writers have the same quality. A lot of them are crappy. Because of this, maybe are worth the effort. -- -- ℱin del ℳensaje.
