Facebook received tens of thousands of potential "sextortion" and "revenge porn" cases a month, leaked company documents show.
The 100-page handbook Facebook gives to moderators reveals the social network receives swathes of reports regarding abusive sexual material, an area where they "make most mistakes", the Daily Telegraph reports.
The documents, leaked to the Guardian, show Facebook users reported almost 54,000 incidents of sexual extortion and revenge porn in January, with the company disabling 14,130 accounts as a result. Moderators escalated 33 cases for involving children.
The files also also reveal that Facebook will not delete videos and images depicting violence, self-harm and child abuse of a non-sexual nature, since they may draw attention to mental illness or be newsworthy. In some cases, it allows footage portraying physical bullying of children under 7.
Recent changes suggest Facebook has only started to ban abusive posts about disabled people and those with serious health conditions in the last few months.
