cashout question

[turnipmonster]

on thursday night (actually 1am friday morning) I requested a cashout with a party skin where I had money sitting around. they still haven't approved my cashout and it's tuesday night. I called them yesterday morning and they said they were doing a "standard security check" on my account and it would be another 24-48 hours. what does this mean? what happens if they deny my cashout or something? it's not a huge amount of money, but not insiginificant either. I've never had a cashout take this long before, not even close.
