seeing this as NO escrow still nemgun, i think this is a potential scam. didn't you notice a lot of scam don't use escrow? but i'm not surprise you supported this project as you were also about to do ICO back then with your scam attempt with blumed.
Before you talk like that,why don't you look in the mirror first,check out your trust rating and explain about this guy giving you red tag for scamming him 10 bitcoin,I don't know if this is true but until that red tags are there don't point your middle fingers because the four others are pointing at you..
