I was present when this happened, we had just discussed how the server was cracked and you wanted to try logging in as someone else. We told you not to.
You then learned about the /freeop command and tested it and it banned you. You then logged in as ashadams and we let you know you can't multi account even for this reason and kicked you.
You then tried to log in as Hasiel but spelled it Haisel.
That is when you were banned, for trying to log in as Hasiel.
I also show GothBoy6 on your IP and that account logged in today.
Lots of issues here dude.
