So I’m not 100% confident that this is a scam, but it sure looks like it. I’ve been contacted by this guy a few times by now. Here’s the email he sent out. Also, I’m pretty sure there is no such thing as the “reverse google pagerank algorithm”.
John Stahl here. I just wanted to drop you a line and invite you
to be a link partner for our website xraider.com.
I’ve found your website with the “reverse google pagerank
algorithm” which indicates that we both would get better google
rankings, when we exchange links.
I’ve already gone ahead and added your site viktorpetersson.com
to our link directory, could you please verify the description

Just thought I’d share it with all of you have in case you have received a similar e-mail. I’m pretty sure neither Matt Cutts nor Rand Fishkin would approve of using the “reverse google pagerank algorithm” even if it did exist. When it comes to SEO, I’m rather safe than sorry and use standard white-hat practices.
Update: John Stahl sent me another message today. The exact same message for the fifth time.
