Why is it OK for one site to do this and when another one does the same thing they are scamming their customers?
As has been mentioned, ultimately what it comes down to in situations where all we have to rely upon is the word of the parties involved in a dispute, is whether you believe the word of the casino or of the player.
I think that
who is making the accusation carries big weight on this forum, as it should. If a reputable member who is known to be a pretty heavy gambler reports having been scammed, their word is going to carry more weight than 5-10 newbies. That's not to say established accounts never lie or newbies always do lie, but its a decent rule of thumb to assign greater credibility to established accounts.
Also, in the case of 1xbit, the owners (1xCorp N.V.) have a telling reputation for unethical conduct among the highest levels of business.

Furthermore, I would say the net bulk of unresolved complaints scattered across the web is far greater for 1xbit/1xbet than Sportsbet, but it really depends on what kind of metrics you're going by...
