‘Peer review ring’ – busted

WUWT
From the Washington Post:
Every now and then a scholarly journal retracts an article because of errors or outright fraud. In academic circles, and sometimes beyond, each retraction is a big deal.
Now comes word of a journal retracting 60 articles at once.
The reason for the mass retraction is mind-blowing: A “peer review and citation ring” was apparently rigging the review process to get articles published.
You’ve heard of prostitution rings, gambling rings and extortion rings. Now there’s a “peer review ring.”
