San Francisco: Twitter has expanded its rules against hateful conduct to include language on its platform that dehumanizes others on the basis of religion. Tweets that go against the new policy will be taken down, the micro-blogging platform said in a statement on Tuesday. “If reported, tweets that break this rule sent before today will need to be deleted, but will not directly result in any account suspensions because they were tweeted before the rule was set,” said the company.
