A Hacker News thread has an interesting post about some of the templates comment spammers use to inject those almost, but not really, real but spammy comments on your site. You know what I mean, if you read them, they will look like a real person wrote them but they make absolutely no sense in the context of the blog post.
To an untrained eye, they often are left on the blog but they are really spam.
You'd think that stuff would be automated but one person in the thread said that a "large marketing company" would hire teams of interns at minimum wage to write up these things throughout the day. The content then would be used to spam Google and other sites.
When this guy posted about it, Matt Cutts of Google, their head of search spam, asked "What's the company" that does this?
Typically, it is hard to get Matt Cutts to personally review spam but Matt is an active user on Hacker News - for now - and it may be your best bet. That is until SEOs and webmasters are flock there and flood it with questions for Matt.
The thing is, you never know what Matt will read and response to on Hacker News, let alone other sites on the internet.
