i think being skeptical is the right move because of how KK operates.
I think based on the typing, the weird almost impossible path-crossing, the prior history of deranged behavior, the excessive spending on anything lolcow related, the links and mentioning of Steve, responding to the 11 month old comment within a few hours, across multiple honey pots, being dialed into kiwi farms to that degree as an "outsider", the previous desire to be recognized and her pattern of retaliatory behavior which she also admits, her admitting to assisting impersonating someone previously and feigning guilt about that, the strange back and forth conversations and how they had both heard of each other, the Assad account posting that WGH blocks people.
To me, it's far beyond 50/50, but i reassert my initial statement. being skeptical is the correct move. I would say the number of coincidences are so far beyond coincidence that I would need to see something hard that says Lisa ISN'T the person.
