Uncheck this if you are not a bot

Ah, that was so much easier than trying to figure out a captcha. :laugh:
You'll never get very far if all you do is follow instructions.
And where is this? Oh, and :doh: :sigh: :wtf: :~ X| :laugh: :^)
What do you get when you cross a joke with a rhetorical question?

Was it like this? Uncheck □ this -> □ if □ you □ are □ not □ a bot □.
My CP workspace: Incredibly trivial and probably useless code samples[^]
No, just the one checkbox.

It's on a website my kid sister probably doesn't frequent.

Can't find it with Google. Is the most relevant result hidden from me?

Wow, that's very ... uhm ... secure. :cool: I once came across a site where they showed a series of pictures with checkboxes and you had to check all the vehicles and leave the rest unchecked. Try writing a bot for that.

Algorithm: Randomly check or uncheck each box. If there's five pictures, then you'll successfully bypass the security 1/32 times. Bots have infinite patience, and checkbox-based security can usually be brute-forced.

Are you assuming exactly one vehicle? I assumed that any, all, or none would meet the criteria. Whoops, no, I see it now, sorry.

There were about 30 pictures perhaps. If you only allowed a few tries before it locked up, it would be pretty secure, I suppose. (I'm not an expert) But nothing is 100% secure of course.

If you display a lot of pictures at once, then the system becomes just as annoying to users as a captcha. Also, you'd have to maintain a large and constantly-changing database of pictures to keep the bot from memorizing which pictures are the vehicles. In any case, defeating the bots is a much bigger task than people realize. If bot writers are willing to create advanced algorithms capable of deciphering a captcha, then they are willing to go to great lengths to defeat other security features, too.

I've seen that with "Kittens" and "Puppies" as well - very damn annoying!
