I could well believe that Tim Higgs is his actual name and he does live 200 miles from Neil Woods. Without doing a careful analysis of it, he seemed to be often posting at weird times, like 3 a.m. East Coast time. It's weird if you have a wife and family and a 9-5 job because you need to be in sync with them. If you're a loner and unemployed, or work a weird shift somewhere, then fair enough.
Toothie could still ID himself if he wanted to, although he seemed to be making a dog's breakfast of it. He could video himself, with face, some kind of photo ID, and voice. People might recognise his phone voice. Or he could Skype someone via Webcam — cam, you know — and have it video'd or captured to show his face and voice.
Anyway, any more trolls around I haven't noticed yet?
