I've no idea what's up with tradeogre, but isn't it a bit early to call it a scam? The site went down yesterday, I suppose if it was just a technical issue then the owner would've posted smth on twitter. Since he hasn't, then maybe it was hacked.. we'll see, I guess.
Yes, far to early to call a small exchange being down for 1 day a scam. They're vulnerable to DDOS attacks and technical issues.
For newbies: never trust a small exchange (especially an anonymous one) with more coins at one time than you're willing to lose.
TradeOgre is working fine today, and their wallet works, which is more than I can say for stocks.exchange.
