What are you talking about? The only scam here is ED. ED listed COSS without "permission" from COSS. ED was given information about the fork and the actions needed to be taken but ignored this.
And COSS ignored that ignoring

Ok, I agree, ED also guilty. So, COSS made scam scheme WITH "ignoring" ED. And what about ForkDelta? 2 exchanges (or more?) appeared too ignoring for COSS to be honest.
