Kyivstar (one of the biggest mobile service provider in Ukraine) has changed it’s CAPTCHA. I don’t realy know why, but I hope they found our site and understood the problem. Understanding is good, but rushing is bad. Instead of think about how strong CAPTCHA should be built they just made primitive changes. It’s now in 100 times stronger then was, but still is easy to beat. Another primitive CAPTCHA was implemented at UMC (biggest competitor of KS). And it’s still there!
