I guess sports betting sites already know that they don't have to lie in presenting the final result of a game because it won't help them gain their user's trust if they lie.
They would be stupid to lie, they don't control the outcome of the game and the result is very visible to anyone who would search and there's a lot of sources, one mistake, will ruined their sportsbook's reputation, they don't want that to happen.
People are really that observant and speaking with new sportsbook then getting trust will definitely be pertaining about giving good offers plus having good design and user interface and this is where
we do mind off most of the time.
Giving best service and just dont give out big hassle or headache to users and they would find out that it do really gives good experience.
