Hacked and banned

Well awhile back around 2006-2007 I had an account on here called Lil range500. I tried logging in, searching members list and nothing came up, but then i googled the name and sythe.org and found some old posts, which i did not create. Also for location says the UK, I never even been there I am from the US. Also, The MSN address in some of the posts and the MSN icon below location are not mine, I have never even seen them before, is there anything anyone can do about this or should I just drop it? Thanks.
