The Exchange ITSELF is not the Scam - it is the owners.
Man, I don't know how you concluded that the exchange (we are talking about garbage from this ANN) is not a scam even though the owner robbed his users. It is even questionable whether this 'unnamed' can be considered an exchange, given that most of its operational work was partially functional.
If you have sound ideas and certain solutions, there is no reason to associate yourself with the 'unnamed' scam, unless you were part of this scheme.
