I don't believe anybody is stupid enough to do that. However, what I believe happened was that someone hacked your account, sold it to some chinese website, whom then resold it to some poor boy that thought he was buying an account. I'd think this is the most likely explanation, as it accounts for the various skilling items on the account. It also explains your account being locked.
yeah that is a good theory
I really think that the OP should be updated more frequently instead of showing pictures of Runescape circa 2005/06. I really want to create a new Runescape Megathread but we already have this one but this one sucks and OP hasn't been on in months.
