Here recently I have seen people sharing these types of stories on my timeline from a site called twistedsifter.com. I took a look at thier facebook page and they have over 335K fans.
I looked at SEMrush and they have been around since 2011-2012, but I have never heard of them, nor have I ever seen stories shared from then. I didnt care enough to look to see if they changed formats or if Viralnova was actually a copy of them.
Also, those sites in the story better get those links nofollowed or Matt Cutts is going to give them a penalty.
I don't think they give a fuck about Google penalties. They spin or just swipe all of their content. I read that the vast majority of their traffic comes from Facebook fanpages. Adding adsense may be an issue, but ViralNova has adsense.
I was being sarcastic.
I can vouch for Jerry's first point. One of my pages has just over 20,000 likes & the standard images reach anywhere from 2,000-5,000 users (depends on what time it's posted) whereas links seem to be always in the hundreds; Facebook has cracked the fuck down on links in an effort to make you "boost" the post which is ridiculous.
