Yeah, for me it was similar. They said they reported some other account with the same name as mine by accident, but it's impossible to have two accounts with the same name on Discord, so I asked what was the name of the account, and they were like "wdym? it's your name" lol

I got a very similar message on Discord a while ago. They wanted me to message another account that was supposed to be a mod, and that account asked me for some personal information. I blocked them both xD
