Just because Nizwa did it, you can do it too, staff don't always do the right thing everytime they do something. Although if you don't know that it wasn't allowed you would be let go with a warning but since you have over 200+ hours ingame you should know by now that cem events aren't suppose to take place in the main dimension, Appeal Denied.
And about Nizwa, Only higher ups can deal with him so don't ask me to do smtg about nizwa or something like that.
