Maxwellhill is an old account. I think online user anonymity is a biggest deal and people realize the value of that. Sort of like op security. So I could see her registering that 14 years ago. But over time she should have realized she need better security. Why she would continue to use it 14 years later is more of a question?

Maybe. The account stopped posting 2 days before she was arrested. And hasn't posted since.
