Update March 22, 2013:
This post was copied from Stackoverflow.com. It mentions the SO author's user ID, but does not say that the content is copied, or provide any link to the original post.
As of June 9th, 2013, they appear to still be ripping content from the Stack Exchange network; this question is copied from Arqade with no attribution:
They're still copying content as of August 4, 2013. This was copied from Programmers, and they didn't bother to strip out the duplicate notice:
The same people run rqgg.net, example:
http://www.rqgg.net/topic/pynmq-why-are-the-bridges-of-klingon-ships-so-steamy.html (from Why are the bridges of Klingon ships so steamy?)
Update Aug 9, 2013
An entire copy of the Movies.SE (give or take a few days) is replicated on rqna.net.
It not only copies the question and answer, but seems to make fake 'user accounts' that aggregate the data taken.
http: //www. rqgg.net/ topic/ nzxp-two-photons-transition.html copied this answer from Physics.SE. This was reported here initially.
Copy http://gaming.stackexchange.com content and even "generously" state it's CC-BY-SA. But no link back.
http://www.rqgg.net/topic/ikyxs-how-to-sort-the-special-offers-list-by-relative-discount.html boldly copies How to sort the special offers list by relative discount?
The username links
http://www.rqgg.net/list/Zommuter.html to a list multiple other questions by me, but there doesn't seem to be any way of knowing it's from ArQAde.
This one is a bit different,
http://www.rqgg.net/topic/rphzq-starcraft-1-disc-2-isnt-continuing-the-installation.pdf, it was posted as a pdf file instead of html. It is a complete copy of Starcraft 1 disc 2 isn't continuing the installation .
As before, there is no recognition of this being StackExchange content and the usernames link to fake accounts.
