Surprise. Few days on the market and no complaints. Scambooks will always act like serious books in the first phase after launching.

The trick is to identify scam before they show their true face. There are a bunch of strong scam indicators I already mentioned. In a few months there will be the first scam accusations by users (confiscated/closed accounts, voided bets and all that stuff). They will collect BTCs until they have enough and one day they will disappear and the URL bitsport.bet will only lead to a 404 site.

Sure. At the moment everything is fine. Come back in a half year or a year from today and you'll get to know their true face.
