Seems there are a lot of websites being compromised as they are being mentioned in these emails.

The spams all look the same, or similar. and follow the same pattern
Two URL’s with different wording saying “get this product here” and one saying “to unsubscribe click here” – as if to indicate the user had granted permission to receive this email, making it legitimate.

The trick is that the spam contains the URL’s of legitimate websites, and mentions legitimate products, eg “find the best school to attend”, so gets past hotmail’s anti-spam

They started off as offers to “find a maid” and various ways to describe cleaning services, but now they keep changing eg teaching degrees, sell timeshares,
etc

But the thing is the email contains URL’s to completely different websites each time. And the URLS point to websites that are for companies that don’t match the product mentioned by the emails.

It seems that the websites listed in the emails must be compromised and the spammers intention is that the user will click on the URL and the compromised website will either directly serve spam advertisements or malware, or issue redirects to a site that will.

Or perhaps its just part of a “increase view counters” campaign… Websites that pay for increasing view counts may be hoodwinked.
