Scholarly journal retracts 60 articles, smashes ‘peer review ring’ - 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.”
