And how do you know that? Do you have a magic ball? I hope that you understand that your comments reflect your lack of knowledge and they have no expert basis and no basis at all. I see no real arguments or facts here. Actually, I think your comments are very immature - and more, if I would be the Xaurum company,  I would demand you to appologize and take back your claims. If you would not, I would take a lawsuit against you because this is a pure defamation!
