Sharkscope's Legitimacy

[ZKoeske]

Hey. I've heard from multiple sources that the legitimacy of Sharkscope has been questioned. I'm not a subscriber but I just started checking out the free 5 searches each day and It appears correct to me. It had all my SNG"s up to the minute, even stating that I was entered in the # of the SNG i was currently playing in. Have there been problems or inconsistencies in the past?
