Some privacy experts say Telegram is not secure enough Perpetrators of these scams will create a public group on Telegram to promote these investment packages that are usually accompanied by fake testimonies and sometimes advertised as being Shariah-compliant. Interested investors will be asked to directly message the representatives to begin investing in the various investment packages offered. Such instructions could actually endanger people — citizens receive air strike warnings via smartphone alerts. For example, WhatsApp restricted the number of times a user could forward something, and developed automated systems that detect and flag objectionable content. In 2018, Russia banned Telegram although it reversed the prohibition two years later.
