No, the visitors had to visit the website in order to get somewhere else.

I can only imagine that people defending these spammy sites have similar sites themselves, otherwise it's crystal clear to most of us that they're redundant sites that shouldn't pollute a search engine index. If people want Groupon content, they should end up on the Groupon web site, not someone simply copying their content (with permission, or not).
