More Spam?

Yes!! already everybody is getting a lot of spam in our email accounts. Thanks to the spam filters, otherwise our inbox would be rendered useless. I just came across this new thing in yahoo mail, where if you give an invalid username and some password, it takes to a page similar to the one shown below. Remember, an invalid id and invalid password. Look at the text I have blocked in the screenshot. Won't it pave the way for more spam?
