You were banned for spamming chat and disrespecting an admin by not listing to her warnings and for leaving and coming back 4 or 5 times to avoid the gag.

You were not permanently banned but for only a few months.

I will lift the ban because it was your first one but I'm telling you right now, next time their will be no warning and you will be permanently banned if you do that shit again.

Have a nice day and welcome to the forums
