I was stunned when I found a website ranking high in sort span of time in Google. I checked their backlinks in SEO Spyglass but it only said 30 or so backlinks. So, I went to ahrefs.com and found that they had recently made 17K+ (and growing) backlinks with in a week. I am sure that they are using some automated black hat seo tool. Some of the example of backlinks are as follows: http://kecskemetivizisportklub.hu/node/37425 http://sindominio.net/piratona/drupal/?q=category/catalogo/online-shopping http://www.centaur-md.com/article/make-sure-you-use-coupon-codes-conjunction-retailer-income-0 50% of these websites were drupal after checking it. Also, the content is unique in each of their post. That is weird. I think they are using some spinning software along with it. Also, not all is Drupal, there are other platforms. The summary is that: Those guys are trying to register on website that allows user to post content and those website which are not being moderated/monitored gets their spammy content posted. But how to do it? Does anyone do it or do you know someone who can do it?
