Because assuming you are human is not so much about the correctest of selections as much as it’s about moving the cursor around the screen in imprecise, non robotic, humanly ways.
These are actually self taught for what is right, based on what most people click, do just for shits n giggs he's talking about peppering the data used for verification with incorrect responses.
There's some anti-CAPTCHA services where they do just that. You pay so you don't have to fill them out. I'm guessing they have a bunch of Indian guys just filling out CAPTCHAs.
Ever since image captchas were created, they've fail me 50% of the time, so I've spammed a lot of random shit that's been accepted. If you get run over by an AI truck, I'm sorry.
Sometimes when I'm on VPN or TOR these little fucks won't let me in no matter what, but instead of showing error message or something, they just keep throwing new traffic lights or bicycles at me
If you are using Firefox, switch your default search engine to DuckDuckGo, haven't gotten a captcha from them once. And right in the search bar you can switch to Google if DDG isn't doing too well on a particular search, I do end up doing that about 5% of the time.
A lot of times those are the backup captchas, the normal one looks at your browser history instead. Using a VPN will change your IP and throw off the history logs, or a setting on your browser
Nah, it's cause you're on an ip blacklist. While lots of people use vpns just for privacy reasons, there is also a lot of abuse from them and the ips get blacklisted frequently.
On its surface, it's a good idea. Website hosts don't want to be inundated with fake traffic and fake data inserted by bots.
But it's entirely unnecessary when your local library or doctor's office is using captcha just for you to fill out a form, it's a bit excessive because it's highly unlikely any type of botnet would be targeting sign up fields on their sites. The attackers wouldn't get anything out of it.
Eh, not that unlikely.
The bots just scan everything they can.
For example, I've seen a guy do some testing with SSH server on default port (22). On average, there was constant 10Mbps of traffic just from the login attempts.
I can imagine it to be similar with websites.
I never know if I’m supposed to click the squares that have a tiny bit of the object or not. I hate the ones like this where you have to do 3-4 screens and then it fails you.
I like some of the newer captchas where it’s like “choose the heaviest animal” and it’s trippy pics of birds, dogs, and elephants.
It doesn't matter because they show the images to multiple people and even shift the images around. If a square is only halfway there some people will click it, some won't and this way you can generate some sort of heat map which is all you need to label your training data.
Ever since I've understood that it accepts objectively wrong answers as long as it somehow seems as if you gave it some thought, I've made sure to hinder the accuracy of models that try to use my data.
It expects you to behave like the other humans in its training sample. Just act like a neurotypical and you'll pass the captcha. And if you can't act like a neurotypical, then you're fucked.
Most of the time they already know whether you're human or robot from your user agent string and the speed of your request. I encountered multiple layer of Captchas if I turned in my VPN and blocked all trackers.
I've found that using a VPN tends to get e caught in more Captcha loops than not. I think google, etc. has gotten better at knowing which swathes of IP addresses belong to VPNs. I thought that maybe it was specifically an issue with NordVPN because it had gotten so popular, so I switched to Mullvad and nope. Still get way more captchas. Still keep it on.
If it doesn't like your answer it doesn't say you're wrong. It just gives you another puzzle to solve. Even if you're right, sometimes it gives you multiple puzzles anyway. Don't sweat the small stuff.
Why does it keep asking me over and over again, then...and then other times, it doesn't. Did I accidentally move my mouse like a robot? Several times in a row?
