We're pretty good at dissecting various techniques, spam networks, etc. But I always like to hear feedback from different places to see how we're doing, uncover new pockets of spam, etc.
I must admit, I always wondered how this network got away with churning burning for past few years (hdwallpapers3d.com, hdwallpapersdj.com, hdwallpapersinn.com, hdwallpapersuk.com, hdwallpapersfan.com, hdwallpaperszon.com, celebritywallpapers3d.com, hdwallpapersonly.com)
Always come up, they offer little value, and are often no more than a few months old, and all made for adsense pages of content ripped from other places. Moment you take one down like you did with hdwallpaperarena.com they just redirected it to hdwallpapersinn.com (which even has the same logo up still).
I just found it a bit of an an odd one given some tactics they apply are outlawed yet they seem to get by, I always see these sites crop up.
Hi, Matt,
If scraped content ranked high is considered a spam, try search for 'atx pinout' (without quotes). The first image result is img.lehaleha.com/medium/17/atx%20smps%20circuit%20diagram17.jpg which is placed on the page circuitdiagramupdate.blogspot.com/2013/08/atx-smps-circuit-diagram.html . You can see in lower right corner of this image url smpspowersupply.com - that's where they scraped this image. Ironically, the original image (shown in smpspowersupply.com/connectors-pinouts.html ) is seen nowhere in google search results.
Here's one that is a little under the radar. The Young Entrepreneur's Council theyec.org posts guest blog articles on well known sites like Forbes, Inc, B2C. Those articles are full of "expert" quotes from members of the YEC with paid memberships - all with links to their sites of course. You'll see the same sites linked to in most of these mostly useless articles. You won't be seeing any quotes or links from people who haven't paid the YEC. Nice little link exchange to get links from really prominent sites.
