Anonibet is catching a lot of heat and may be wrong, in this current case, to be seen, but one of the reasons they were rated so high is that in my dealings with Michael, he has been 100% honest.
One person was overpaid 15 BTC by Anonibet. When the player posted about it, Michael took full responsibility for the mistake. Michael said that the player wasn't a scammer. After that the player did pay Anonibet back. the player made a bet for 15 BTC and said if it won that he would pay back Anonibet. The bet won.
Anonibet didn't even bring the case to the forum. The player stated that he was overpaid.
