I reckon it's probably just a publicity stunt.

No one had heard of worlds.com, no one gave a damn who they were or what they offered.

Now almost every one who worlds.com would want to offer their service to knows them and will remember them for some time.

The phrase "There's no such thing as bad publicity" comes to mind here. What it all boils down to is that worlds.com has just saved themselves millions of dollars on advertisement and had a one in a billion chance of scoring some settlement money.

Smart move worlds.com, although I do not at all approve of your method.
