A few spambots have basic math skills, allowing them to bypass capchas that use a simple math problem.

But one weakness of computers, is that they cannot to anything that isn't absolute. Meaning that if a number divides itself by zero, it will either terminate or crash the program, or return a Cannot Divide by Zero error.

So I was thinking, as a capcha, maybe you could have something like 5 / 0, when the bot tries to do the math, it will either crash, go into an infinite loop, or get stopped right in its tracks.

Think it would work?

It's a nice thought getting it stuck in a loop but I'm guessing it'll just terminate and move on. Anyway it'll create more problems for humans haha. Honestly! What's the right entry? N/A? Infinity?

You can have no doubt that any number divided by 0 is infinity. And dartz have thought so beautifully. This is a very good idea man. I like this.
