I can do most fairly easily, but the new trend for the Google captchas that often contain bizarre symbols that equate to nothing my keyboard can produce without resorting to ASCII code? Yeah, I'm refreshing that shit 400 times in a row until I get "cat gilded" or something else that at least resembles words.
Yeah I think they are starting to run into a laundry list of difficult scans and not so many easy ones. They have to have a sorting probably, where they see an OCR grab had a lot of fails but they looked easy so he marked them so, and another page scan was all screwed up and marked all the errors hard.
A lot of the ones I'm even able to do are still pretty bad looking. I think they probably ran an even split on probability of the range of difficulties, but misjudged how often people would even bother on some hard ones and skipped and settled on easy.
And a lot of people just skip until they get one they know they can solve no problem, avoiding even one failed attempt. That chews up through them.
I wonder if it'll be getting to the point where they splurge on another massive run (not sure if they've been getting more scans or not) or if administrators will take notice of a rampant increase in difficulty and switch to a different captcha.
(this was all about Google's captcha service)
