Twitter, Google, Facebook are changing their policies to prevent bullying and improve accuracy. Bobbi Rebell reports.
Twitter is making a big change to its policy to curb bullying and bad conduct. The company says it's expanding the "mute" option to allow users to block tweets based on keywords, phrases, and content. The news comes a day after other tech giants - Google and Facebook - said they are trying to stop the spread of "fake news" by changing their advertising polices and cutting off websites that produce them.

So, it has some symbolic value. They're getting bunch of attention. To be honest, it's not clear how well it will work, but it can't hurt." Google, Facebook, and Twitter have been facing criticism over the role they played in the U.S. presidential election by allowing the spread of false and often malicious information that might have swayed voters decisions.
