For what it's worth, admittedly not much, I seriously doubt SWK is one of Skeeter's sockpuppets.
1. Skeeter usually admits to them, to the point that he's proud of them, despite the fact he should be doing his best to closet his shame.
2. He's not offensive enough.
3. There are similarities (the use of "Lol", with the first letter capitalized, for example), but though I rarely give Skeeter much credit for being an intellectual, if his goal here is to create an independant sockpuppet, I'm sure he'd have the since to put as much distance between himself and his creation as possible.
4. It's just not his style.
I'm not SWK either.
