I have two websites that have created dozens of backlinks to my website. votefrankharris dot com and a similar ddswhite dot com. The first website's backlinking pages redirect to malicious pages/sites. The sites appear to no longer be in use (I guess Frank didn't get elected). There's a fairly exhaustive list of these spammy sites here.
My question is, what is the point of someone doing this? Are they hoping that curious web admins will click on their backlinks and get infected? Is this some kind of blackhat SEO trick?
