An anonymous reader writes: Social media website Reddit, known for its commitment to free speech, will crack down on online harassment by banning or suspending users who target others, starting with those who have directed abuse at Chief Executive Steve Huffman. Huffman said in an interview with Reuters that Reddit's content policy prohibits harassment, but that it had not been adequately enforced. "Personal message harassment is the most cut and dry," he said. "Right now we are in an interesting position where my inbox is full of them, it's easy to start with me." As well as combing through Huffman's inbox, Reddit will monitor user reports, add greater filtering capacity, and take a more proactive role in policing its platform rather than relying on community moderators. Reddit said it had identified hundreds of the "most toxic users" and will warn, ban or suspend them. It also plans to increase staff on its "trust and safety" team. On Reddit, a channel supporting the U.S. Republican party's presidential candidate Donald Trump, called r/The_Donald, featured racist and misogynistic comments, fake news and conspiracy theories about his Democratic challenger Hillary Clinton, along with more mainstream expressions of support for Trump. Many of those supporting Trump were very active, voting up the r/The_Donald conversations so that they became prominent across Reddit, which is the 7th-most-visited U.S. internet site, according to web data firm Alexa. Last week, Reddit banned Pizzagate, a community devoted to a conspiracy theory, with no evidence to back it up, that links Clinton to a pedophile ring at a Washington, D.C. pizza parlor, after it posted personal information in violation of Reddit policy. Huffman then used his administrative privileges to redirect abuse he was receiving on a thread on r/The_Donald to the community's moderators — making it look as if it was intended for them. Huffman said it was a prank, and that many Reddit users, including some Trump supporters, told him they thought it was funny, but it inflamed the situation.
