The lagging part only happened once or twice, but you know how you can press the up and down arrows to cycle through the things you said/typed? Well some times i do that to get back to a command or something else but I count wrong and go back to something I already said. Ill pay more attention for now on. Also while advertising, would it be OK if i wait until my text is off the screen to say it again or after 2 min?

I was playing last night and nothing was wrong, I was just trying to sell a spider XP FARM  I also bought from "Beast1n1tup39", also last night. Then I got off to go to sleep, I woke up this morning to go to work, and when I got back I wanted to play some Minecraft, so I turned it on and clicked "join Server" and a message came up saying the ban hammer has spoken. Why am I banned? What did I do wrong? Please help.
