Got Banned

I was randomly banned for doing nothing in the online chat! As soon as I got on I said "anybody have any skin requests?" and then someone else said "lol minecraft1337 thats just what i was going to say" then i said back "lol"
and then someone said "no requests here" and I said back "uggghhhhh" because i was really wanting some skin requests. When I look back at my screen it said I was banned! I tried getting back on 2 or 3 times but it still said i was banned. I have no idea why I got banned so someone please tell me if it was like something I said. It would also be helpful if a moderator read this and unbanned me if I really didn't do anything. PLEASE READ AND HELP.
