For example, WhatsApp restricted the number of times a user could forward something, and developed automated systems that detect and flag objectionable content. In the past, it was noticed that through bulk SMSes, investors were induced to invest in or purchase the stocks of certain listed companies. Despite Telegram's origins, its approach to users' security has privacy advocates worried. In 2014, Pavel Durov fled the country after allies of the Kremlin took control of the social networking site most know just as VK. Russia's intelligence agency had asked Durov to turn over the data of anti-Kremlin protesters. Durov refused to do so. However, the perpetrators of such frauds are now adopting new methods and technologies to defraud the investors.
