Journal that holds record for retracted papers also has a problem with editorial board members. 

snip~
Almost every scientific journal has to retract a paper once in a while. But at Tumor Biology, when it rains, it pours. Last month, its former publisher, Springer, announced that the journal was retracting 107 papers all at once, after finding that the peer-review process had been compromised. It was the third mass retraction at Tumor Biology, which now holds the unenviable world record for most retracted papers, according to Retraction Watch.
