Hi all,
I have general question, I don’t know where to put this on forum.
I question is, many site ask some text to enter while posting commentsa long with login Id or some credentials. I do not understand the logic behind it. Can any one make me understand?
Regards,
PPCC
Normally this is to make sure that you are a real person.
By putting the picture check in (where they make you enter the text in the picture into another textbox) they can stop bots from accessing the page.
You mean Captcha? http://en.wikipedia.org/wiki/Captcha
Yes, probably a Captcha.
There is a blight of web-scraping going on that fills forum sites with spam and worse. Those mechanisms try to defeat such automated attacks and prevent the "roadside litter of forum spam."
It's also why I don't answer posts about using the WebBrowser control.
