I have to jump to Tasha's defence here.
She's a compulsive sock creator and something of a fantasist, and maybe a compulsive gambler, but I don't believe she will be stealing the gift cards.
I believe she finds it a convenient way to anonymously send funds (she just PM's the cards token code) when she's unfortunate enough to lose a badly misjudged freeroll.
If the 'scam' is anything it's just her way of buying some of the attention she craves.
It will be interesting to see if she will agree to settle with other forms of payment... If she loses.
