If you do decide to visit any of these pages and/or click on any of these links then be prepared for a barrage of pop-up windows!
What appears to be happening is links to target, legitimate websites are being generated and displayed on these fake blog sites. The spammer then visits the target sites, causing an entry to appear in the legitimate websites access log with a referrer value pointing to the fake blog site. When the webmaster visits the fake site to see why they've been linked then they unwittingly provide another incoming link for the spammer.
As an experiment I uploaded a webpage to some free webhosting space. On the webpage was a single link to one of the fake blog sites. I visited the webpage and clicked on the link. Lo and behold, my webpage address had been added to the list of incoming links.
I then also visited the same fake blog site by entering its URL manually into my browser. By visiting a website in this manner you don't provide a referrer value. I noticed that this caused the list of incoming links to decrease by one. I refreshed the webpage and noticed another link had gone from the list. I continued to refresh the webpage until there was only one link left. Each of my visits was providing an empty referrer value and this was taking the place of one of the existing links! However, after a few minutes had passed I refreshed the webpage and noticed the incoming link list had grown again. This time it was showing URLs that clearly indicated that it was due to someone viewing their access logs online and clicking on the link to visit the webpage in the referrer value.
All of these efforts by the spammer seem to be to attract incoming links and traffic. Current PageRank values for these fake blogs remains low. Whether or not they will be successful remains to be seen.
