Yesterday and this morning I was trying to ask a question at StackOverflow.
System prompted me captcha form, but under the (funny) video I was unable to see the captcha insert text box; only the "I'm a Human Being" appared.
I got a screenshot, but upload of images failed here now. After trying many times with different browsers, just 2 minutes ago my post went online, without requiring me captcha step again.
What's the problem?
Someone can explain me?
