For years, email spammers have been looking for ways to encourage people to click on their links. And for years, Google has been a target. Why? Well, when someone sees a link that has google.com in it, people trust it. So over the years, Google URLs that redirect to other sites have been a target by spammers.

It looks like some spammers have taken a liking to Google Reader – we’re currently trying to find the best way to limit this kind of automated abuse without impacting the experience of real users such as yourselves.
