What to do about another form of spam I found

[bvi]

One of my clients brought to my attention that one of their competitors is using their propriatary products to spam Google and rank well. Basically all this competitor has done is post a long, text rich page (no navigation) that talks first about all the products they sell, then about all the products they do not sell. They are ranking well with this page in Google for my client' products. The page is of no value to anyone finding it and is very confusing. I have reported to Google-complaints already. Any other ideas what can be done?

How is it spam? I personally think this is a very good marketing strategy
