"Uhmm how do I say this... Please don't be mad. I connected to a public wifi days ago and somebody else had access to my account but he couldn't change my password because 2FA was enabled. Then he made fun of my discord account and reported some random people and on servers and that includes you. It is stated here that our accounts could be suspended and our IP addresses could get limited from accessing discord. Could you help me explain to discord staff that the complaints were false? I hope you could help me sort it out because I just realized that its not right to leave it be and it also alerted me that you wouldn't get notified about it, so I messaged you to tell you about it"
If anyone on Discord, especially users you haven't spoken to in a while, sends you such message on DM, you should block the account and write an email on the Discord support website. There is a possible real hacker attack scam going on…
