Let's start from the beginning. A discord user by the name of zoom#3513 joined my server. I expected that he came from my forum post.
After he gave me his Minecraft user, we whitelisted him. Suddenly my friend's mc account got logged out it said: Account logged in from another location. Later it happened to my account aswell. All of a sudden my friend's account joined (Mikken12) I asked is that you? He replied no. Then my friend msg me through discord saying he changed his mc username. So I checked my server and realised that an unexpected username was on my whitelist mitankOm appeared. Immediately I stopped the server. When I restarted it he joined instantly together with my friend. I instantly banned him. He is now replying to my threads with odd messages beware.
