Anyone backlinks from hacked FaceBook widgets?

[ShockoeCommerce]

I was going through my backlink profile the other day and started noticing a huge number of new back links, like 100k. Digging through them, I am seeing a lot of links that are inserted in Facebook feed widgets. You will see the link at the bottom of the widget.

From what I can see, a lot of these links are all in this format, all on European domains, all running WordPress. Doesn't seem to have anything do to spamminess. Had domains that were on blacklists, some not.

Anyone seen anything like this before? The only thing I can think of was maybe an automated hack bot that inserted the link when it was able to get in?
