Man, that thread is ridiculous. I don't see any sign of sock puppeting. The OP stop posting some time ago. Also, she stop posting prior to the poster outing her for having an SUV (if that is even an accurate "outing"). It's entirely possible the OP hasn't see most of the discussion.

If you feel like settling a sock puppet debate, please do!
