There have been some cases and accusations against casino that have been piling up, but as far as I can see, most of them have been successfully resolved now. Although, I wouldn't really say that their reputation was completely destroyed since bc.game is an old and somewhat reputable casino.
BC.Game's controversy has been a rollercoaster ride so far with them falling and rising back up in a short period of time. Personally, I still don't trust with them with huge amounts which is why I am sticking to small amounts.
They are way, way better than sites like 1xbit and Bitstarz though, but I am cautiously optimistic about them currently.
