Facebook is failing to shut down groups on its site where fake Amazon reviews are sold, Facebook was urged in June by the Competition and Markets Authority to probe the sale of fake reviews via these groups.
Facebook claimed to have disclose several active groups who recruited people to write false testimony, Facebook had removed almost all the groups that were reported to it and was still investigating the problem.
On Facebook recruiters added more than 55,000 posts to the groups that offered free products to people who wrote highly-rated reviews on Amazon.
“It is deeply concerning that [Facebook] continues to leave customers exposed to poor quality or unsafe products boosted by misleading and disingenuous reviews,” said Natalie Hitchins.
Hitchins said Facebook needed to take more action against all the groups that had been talked about and be more “proactive” in finding and closing other groups.
“Facebook must take effective steps to deal with this problem by quickly removing the material and stop it from resurfacing,” he said. “This is just the start – we’ll be doing more to tackle fake and misleading online reviews.”
“We don’t allow people to use Facebook to facilitate or encourage false reviews.” spokesman said.
It said it had removed nine of the 10 groups reported to it and was investigating the remaining one, it said.
The social network added that it was improving the tools and technologies it used to find the groups.
