As long as the captcha doesn't want us to solve these problems .... it looks like a good way to prevent spam. But aren't bots nowadays capable of detecting the simple captchas?
Yep, some bots probably will be able to figure out the math CAPTCHA. In fact with complex OCR, they can even figure out the wavy letters CAPTCHAs. But oh well, it will keep some of them away.
I have no problem with it at all. Thanks for all the work you've put in trying to deter the spammers. I'm sure it will pay off and is very much appreciated by the member here.
Had you gone with Goggle's wavy letter crap instead of math questions I might have a different answer for you. I have the worse time making out that letter nonsense.
I'm cool with it since that was one of my suggestions
Would they also be able to use a bot for a CAPTCHA that uses a question format (yes, like CPF)? That seems a little more complicated but it would be easy answer for anyone actually reading it.
THANK YOU for not using the wavy letter crap Craigslist uses. I have to refresh that so many times to find something I can actually decipher.
There are other types that require some human intelligence, such as "Which doesn't belong? - Apple, Pear, Stove, Banana". I might take a look at those too.
Boo…don’t go with that. I’d have a 50/50 chance of getting it right since stove or banana belong with the apple & pear unless it’s in a salad. My instinct says “stove” but my brain tells me “banana” since bananas aren’t fruit but actually an herb.
This seems nicely implemented to me; like others have said, the simple math question is a lot better than the unreadable 'enter the words' types of captchas. I hope this helps keep the Spammerz out...
