In standing with typical internet history, the odds of "Samantha" actually being a member of the female sex are pretty low.
...I will second that observation from "BitCoinAddict": "pretty low".
But not zero.
...Not zero, because "Samantha" is offering a perfect demonstration of what most females do with men: use clever manipulation to get money, or other things of value. So why not try those same techniques on BitCoin forums. Obviously, "female wiles" are working here, too, no matter if "Samantha" is a real female, or not.
