A company behind a health care information website under fire over inaccurate, plagiarized articles on Thursday said it had temporarily suspended operations of eight other niche online services.

It emerged this week that articles on DeNA Co.'s website Welq were not properly fact-checked and that outside contributors were told to write stories by taking information from other medical websites and rewriting it.

"It was seriously wrong to provide medical information in an inappropriate manner when it needed to be handled with extra care," DeNA CEO Isao Moriyasu said in a statement Thursday.
