I do not remember when I last chatted in Yahoo Chat rooms because its been really long. I remember that one of the reason for not going to chat room was spam bots ie. some automated computer programs who used to either advertise for some site or just simply spam in chat rooms.
But Today I happened to enter chat room without any reason and found... that Yahoo has implemented Captcha .. so it means can really enjoy chatting without spam bots ?
So how it works, you usually log into chat rooms but it will first ask you verify by giving you a link in chat room then you will be taken to a webpage where you have type few words as given in picture and then only you can chat !!
Below are the screen shots..
The Verification Link Given in Chatroom
And now you have to verify yourself as real human by typing those letters given in image into the text box.
Do give me your views .. if it really improved yahoo chat recently ?
