Seriously, some are almost impossible! Way too ambiguous. And sometimes you have to go thru like 12 or 15 times and they're all this bad or worse. What da fuck is this shit!
damn ace...that looks like some darknet shit going on...wheres that from? ftr...until I clicked this thread I did not know what those things are called. i read somewhere that some sites use peoples interpretations to decipher and digitize old manuscripts and documents
that one was from moonbit.co.in not sure how they make them, i think they just make some shit up. There are a few code libraries i believe that can be used to write code for what you'd call "computer vision" and with that analyze text, so in case anyone would incorporate such a thing into a bot script, some are made ambiguous enough that even if you can read it, you need a "human experience" to interpolate the intended meaning of the phrase. sometimes they are actually mispelled from what is intended, and you're supposed to catch that and type in the correct phrase .. a computer program would probably be coded to take it completely at face value. But even as a human, sometime it's hard to tell. that was one of the worst ones i've seen in a while tho, i can actually bust through most of them pretty quickly, sometimes it helps to slant your head a bit, but this one I didn't even attempt. Somewhat ironically, the hard ones would tolerate any errors, but some of them are pretty lenient and allow an error or two, or don't pay attention to case and of course these are the easier ones already.
You've seriously never seen a box that makes you enter a bunch of numbers and letters to proceed? They are EVERYWHERE on the internet... probably here when you sign up, when you sign up for email or.... well, almost anything else.
I used that CAPTCHA service on my site. Pretty cool idea actually and most of them are fairly easy to read if you are human.
unless you run a site with forms or similar data collection, then getting hammered by a bunch of bots is incredibly more annoying.
they're a way to try to stop bots from loggin in and spamming sites. and more particularly online 'secure' storefronts use them. obviously the best security is to not shop on line at all. but if you live someplace where there just isn't any place that has what you need, and you don't have a car, that's what there is these days.
of course, a lot of bots are able to get by them anyway. which i guess is why they make them as undecipherable as in the OP.
