Do you own the website that you are trying to remove from Yahoo?
Yes, I can help you.
If you're a webmaster and would like your website removed from the Yahoo Search index, there are two steps you'll want to take:
In order to remove the website, you will need access to the website files and have the ability to edit the files according to the steps that I have provided.
Alternatively, you can have the website "hidden" or taken down from Godaddy and it will not link to your website on Yahoo.
Since you cannot remember your login information to Godaddy, I would suggest that you contact them at 1-***-***-**** so they can look up your website and help you remove it from their database.
