A player was overpaid 15 BTC. Anonibet took full blame for the mistake. They even went so far as to say that the player wasn't a cheat. I don't remember the exact wording but it had the same meaning. The player did pay back anonibet. Anonibet had an outage. Every player that emailed anonibet received .1 BTC for the down time. Anonibet opened in 2011 and has a maximum withdrawal of 500 BTC.
Last time I checked the maximum withdrawal limit on Anonibet was 500 mBTC, 0.5 BTC that is.
I'd also like to add that the recent allegations does not look good, at all. Until I see some acceptable explanations I'll move my betting business elsewhere.
