I have contacted and eventually chatted with several people that had their money stolen by Bitcoin Fog, including myself.  If support ever answers a message do not expect any response that actually addresses your concerns.  Instead they will more likely belittle you and in my case they even acted annoyed that I was bothering them over such a small amount of money as they put it.  I guess it was big enough for them to steal it though.  With many of the people I emailed and eventually chatted with... they told me they simply got tired of dealing with it especially since it was clear they had lost their money and were not going to get it back.  Many did not even warn other people.  I wish I had some forewarning, I guess I did not dig hard enough on the forums before I sent them my money.  I wish I had hunted hard for information like this before I sent them money rather than after they ripped me off.  Being violated (ripped off) and angry about about it really motivates a more thorough search I guess.
