Who was it then? I have brothers that I share the computer with. We all use this site and I know which accounts are theres. It would most likely be a brother or sister of yours if it wasn't you, although seeing as you said your sister was going to make an account, it could possibly be her, in which case you should set her straight. The only other possibility I can think of is that you went to an internet cafe. You would have had to take turns on the computer meaning you allowed him to act like a jerk. I still think it's you or one of your brothers and/or sisters seeing as option two is very unlikely. If you are truly innocent, please elaborate to me on what your situation was and what happened then.
