Following searching various things for this question, I found:

http://askubuntu.greatknow.com/questions/294850/does-canonical-have-other-deals-with-companies-like-the-amazon-search-feature

which seems like a mirror copy of:

Does Canonical have other deals with companies like the Amazon search feature?

Now this makes me thing of (atleast) 2 things:

• Is this site here to do harm? (e.g. a SE user signs in through it and gets their account nicked)
• Isn't there copyright infringe stuff that might cause issue
• Is it affiliated with Ubuntu/StackExchange anyway?
• Add advertising? (I have three ad-blockers turned to max so can;t check this easily)

I have in the past found various weird sites that contain shortened versions of StackExchange questions/answers and link to the main post (e.g. this site), this is the first that seems to be trying to copy it exactly....

EDIT:

At the bottom it links to http://photoemblem.greatknow.com/ http://pasteubuntu.greatknow.com/

http://www.greatknow.com/ appears to be some weird Q&A site.

ANOTHER EDIT:

It also updates to keep up-to-date with the current site....

(compare http://askubuntu.greatknow.com/questions & http://askubuntu.com/questions then panic...)
