One of our competitors has somehow spammed our full company name into the Google index like this:
When we visit the link, though, it goes to a "not found" page. Attempting the view the cached page from Google results in a 404.
The net result of this is that they are the 3rd organic result when our company name is searched. It appears they have a method for stuffing the index with our company name for their own benefit.
How did they do this, how do we prove it is intentional and deliberate, and is there anything that can be done to stop it?
