With the exception of yes/no propositions, I have never seen a sportsbook put up only one side of an event for wagering. DB seems to do this on a daily basis.
This.
It's not an error from the "odds provider" (who says they even use one? unlikely that they do since their odds are worse than any other book) and never has been.
"You can bet on other sites" is irrelevant. This is about the ethics fairness scruples of DB and the obvious fact is they are unethical unfair unscrupulous and we're here to remind people of that.
PS: I know you guys (arallmuus, Josepht, bitbaby) don't really care and just want to sig advertise, but if you continue to drag on the conversation we'll just keep responding too and remind people that DB is primarily a trap and only secondarily a contributor to the BTC sportsbook community.
