Former Reddit CEO Ellen Pao has accused the company of making money off hate.

Pao made the accusation on Twitter after the company published an open letter condemning racism.

Current Reddit CEO Steve Huffman wrote in his letter: "We do not tolerate hate, racism, and violence, and while we have work to do to fight these on our platform, our values are clear."

But in response, Pao - who served as Reddit's CEO from late-2014 to mid-2015 - admitted she felt the need to hold the company to account.

She wrote on Twitter: "I am obligated to call you out: You should have shut down the donald instead of amplifying it and its hate, racism, and violence. So much of what is happening now lies at your feet. You don't get to say BLM when reddit nurtures and monetizes white supremacy and hate all day long (sic)"

Reddit has faced long-standing criticism of not doing enough to tackle racism on its forums.

But during her own reign at Reddit, Pao banned five subreddits for fostering off-site harassment.

However, she left the company in 2015 amid complaints of censorship.
