I sent in an obtainable high score with a ridiculously low time. Well, I sent two scores on the same game (Well I used AoB.. I'd never make such a ridiculous mistake in SS). One was low enough to sneak past, but the higher one got reviewed. I was on tenterhooks all week. What I found a few days later was, my lower score that had snuck past had been removed from the high scores table, so I knew that they had to have seen the higher score. And I hadn't been frozen. I've pretty much already gotten all the game avatars, so I'm playing legit on that account now. I was freaking out, but I didn't suddenly move all my items to another account. I let my fancy pets stay put so as not to make it look like I was saving my ass. I knew it'd just turn into a chain freeze anyway. I used up the NP I had on the account buying stuff I always wanted
I'm guessing my account has been flagged for suspicious behaviour, so I'm not going to do anything now to draw even more attention to it. Of course there's the possibility that they'll ban me in one of their mass freezings, but at the moment, it looks like I'm ok. Hopefully, it'll work out the same for you.
