How can I get this site to quit appearing in my mail box it is gross.?

If you are referring to mail in Yahoo, Spam them.

Set up your Spam Protection.

1. Click on the "Options", Mail Options link in the upper right of your yahoo mail page.

2. Click on "Spam" in the left navigation bar.

3. Fill out the form and click the "Save Changes" link at the top left.

Once you have this set up, each time you see spam or mail that you want to block, check the box next to it, go to the top of the email list and click the "Spam" button.

Note: Every message you report trains your Spam Guard filters to work better for you. The messages you select in this way will be deleted and reported as spam.

The senders of the messages will be added to your "Blocked Addresses" list.

If you are referring to e mails from an unwanted source, then you can try blocking their address in your e mail system. Please go to the spam or block option of your e mail system and enter the details that appear after the @ sign of the offending mails. Please ensure that you preview and submit the details you have entered, as required by the e mail system. This might help in blocking mails received from that address in future.
