I've deleted this web page after having received the following email:

Dear Peter Ponzo,

I serve as copyright counsel for Yahoo and write to you with respect to your site, specifically the page located at

Yahoo offers certain services on its website, including the Yahoo Finance service available at, subject to its Terms of Service, located at It has come to our attention, through a data partner, that your page located at provides a tool and instructions for using the tool to enable users to hack the Yahoo Finance site.

While it appears from your website that you may not be aware of the infringing nature of your conduct, this letter serves to provide you with specific notice of such. Yahoo contends that your use and distribution of the tool and the content located at constitutes a breach of sections 6, 12, and 18 of the Terms of Service (among other provisions), gives rise to unfair competition, and induces others to breach the Terms of Service. Furthermore, it likely constitutes an interference with Yahoo’s contractual and business relationships with third party data providers. By interfering with these contractual and business relationships, you are potentially harming the ability of other users to obtain the benefits of the services provided at the Yahoo Finance site.

For the above reasons, we request that you immediately do the following:

1) Remove and delete the page located at;
2) Immediately cease any further distribution of this content; and
3) Provide a representation that you will not engage in further misappropriating activity as it relates to Yahoo Finance content

Nothing contained in this letter constitutes an express or implied waiver of any rights, remedies, or defenses of Yahoo, all of which are expressly reserved. Please feel free to contact me should you have any question or concerns. I look forward to receiving your response.
