A judge in the U.S. District Court for the Northern District of Georgia last month rejected Wal-Mart's request to take over the domain names "Walocaust.com" and "Walqueda.com" saying there was no way to mistake that the content on the sites, mostly anti-Wal-Mart opinions and products such as Walocaust T-shirts, were meant to criticize the company, not profit from the use of its name.

The legal wrangling did cause Walocaust.com to post a disclaimer at the top of the site saying it has no affiliation with Wal-Mart, a step that Morgan has already taken at Goldmansachs666.com.

A spokesperson for Goldman Sachs declined to comment on the lawsuit but said the letter was sent to Morgan to protect the Goldman Sachs trademark.

"We don't have an issue with his comments, those are his views," she said.

She indicated that the prior lack of a disclaimer at the top of Morgan's Web sites to say that the site and owner had no affiliation with Goldman Sachs played a part in the letter, but declined to comment on whether the inclusion of a disclaimer, which is now there, would mean Goldman Sachs will not proceed with legal action.
