Ukrainian President Volodymyr Zelensky said in a video message on Tuesday that Ukrainian forces "destroy the invaders wherever we can." A Russian Telegram channel with over 700,000 followers is spreading disinformation about Russia's invasion of Ukraine under the guise of providing "objective information" and fact-checking fake news. Its influence extends beyond the platform, with major Russian publications, government officials, and journalists citing the page's posts. Meanwhile, a completely redesigned attachment menu appears when sending multiple photos or vides. Users can tap "X selected" (X being the number of items) at the top of the panel to preview how the album will look in the chat when it's sent, as well as rearrange or remove selected media. However, the perpetrators of such frauds are now adopting new methods and technologies to defraud the investors. In addition, Telegram's architecture limits the ability to slow the spread of false information: the lack of a central public feed, and the fact that comments are easily disabled in channels, reduce the space for public pushback.
