Why was I Banned?

[BlackburryKush]

I tried to log in just now and it told me." The Ban Hammer Has Spoken!". Why was i banned? I don't cause people trouble? I'm friendly to everyone and i don't mess with other people. :/
Can someone please explain why i was banned?

Another user on your IP Address was banned and so your IP was banned as well. I have lifted the IP Ban.
