I get messages everyday in Telegram.
Most of them approached me as investors, group admins or affiliates.
One way to detect them is that they will approach us first. And they always start with 'Hey User'.
Real investors or admins dont simply approach other people until we ask for their help first.
Yes, I have been scammed 2 months ago when someone made an interview with me to manage their help desk and solve the problems of their customers, and they asked me to download their management client, but I recognize the risk and my antivirus catch the malware.
