Comment Spam

Got more comment spam last night! Even with Captcha turned on! (Thanks casey) Time to try something a little different.


Captcha and 0.95

I've been running .TEXT 0.94 for a couple years now. The amount of comment spam lately has forced me to update to 0.95 and implement Dave Burke's version of Captcha. I'm hoping this cuts down on the amount of spam I'm seeing...fingers crossed!


GOTCHA example

clock July 23, 2005 05:05 by author Admin_disabled

Here's a quick example of the GOTCHA app I talked about yesterday. It's a class library and test windows form app. It takes a background and as many images as you want. Then it randomly assigns numbers between an assigned Min and Max to each image, and rotates them. I also make sure that there is no image overlap (some could be good though). Finally it generates the question and the answer. The question is in the form "What do you get when you add the {0} and the {1}?"
Where 0 and 1 are the names assigned to the images. Here is a screen shot of the test app:

Let me know if you use this on your web page or blog!



GOTCHA

With regards to my previous post, here's what I'm thinking:


 CAPTCHA

"If you add the crown and the cake what do you get?"

Any comments?



CAPTCHA

clock July 22, 2005 07:41 by author Chad Albrecht
casey talks about picture CAPTCHAs in a recent blog. What about putting various pictures on the same jpg. Let's say a hat, cake, drum, jar, spool of thread, rocket, etc. All things that have very similar signatures. Have the app randomly rotate and place each item all over the picture and draw random numbers on them. You would also use colors that make edge detection more difficult. Then you ask the user "What number is that hat?" further "What do you get if you add the hat and the rocket?" Any thoughts?
