During that six-month period, Facebook removed more than three billion fake accounts - more than ever before.
More than seven million "hate speech" posts were removed, also a record high.
For the first time, Facebook also reported how many deleted posts were appealed, and how many were put back online after review.
In a call with reporters on Thursday, chief executive Mark Zuckerberg hit back against numerous calls to break up Facebook, arguing its size made it possible to defend against the network's problems.
"I don't think that the remedy of breaking up the company is going to address [the problem]," he said.
"The success of the company has allowed us to fund these efforts at a massive level. I think the amount of our budget that goes toward our safety systems... I believe is greater than Twitter's whole revenue this year."
