REPORTING SPOOF

If you received this message after attempting to report an email that appears to have come
from eBay but actually directs you to another site, you must forward the message to us
again by using the forward function of your email program. Make certain that
spoof at ebay.com is in the "to" 
field. Do not alter the subject line, add text to your message or forward the email as an
attachment. 

We appreciate your assistance in this matter and apologize for any inconvenience this may
have caused you.

Sincerely, 
 
eBay SafeHarbor Team

Tips to Avoid Spoof:

To help our members better protect themselves from spoof Web sites, we have developed a
new feature for the eBay Toolbar called "Account Guard." Account Guard includes an
indicator of when you are on an eBay or PayPal Website, buttons to report fake eBay
Websites, and a password notification feature that warns you when you may be entering your
eBay password into an unverified site. To learn more about the eBay Toolbar with Account
Guard, open a new browser and type www.ebay.com/ebay_toolbar into the address bar. Note
that eBay will never send you an email that includes a download as an attachment or a link
that goes to a page with a download.

eBay also recommends that you ensure that your Web browser, operating system, and virus
protection software are up to date. Check for updates at the "Windows Update" link on
www.microsoft.com and scan your computer for viruses often.
