All the above usernames are fake and it's hard to take all the usernames since you need a unique mobile number to take a Telegram username. Not sure if more fake usernames would generate in this way. Any reasonable members should realize the difference between O & 0 if they are familiar with the Telegram scam. It's hard to prevent Telegram impersonators, changing forum username was my little try to prevent them.
