Ok trading the santa to ur friend, then back to u SHOULD be legal, by the laws of the common sense anyway. After all, it can be easily explainable. You gave ur friend ur santa for his bday. Then, he decided to give it to the poor (which happens to be ur second account, but no one knows that) and that's how u end up with it. With all the trades going on at every instant in Rs, theres no chances ur going to get banned for that. It's much more safer than drop trading too. And if u want to be sure, say "For u bday" when u accept the trade. Then whe n ur skiller receives it ur friend can say "For the poor". There u go, story, explanation, proofs, woot.
