A new CAPTCHA system has been put in place by the Civil Rights Defenders group. If you fail to answer a question correctly, you will be told to wait five seconds for another question to be answered. The group hopes to promote and empower its human rights partners in the fight for human rights. But there is a very limited selection of questions – and all the ones I saw required a negative response. A wider range of questions for web users would probably be a more effective challenge for automated bots.”]
