Looks like there is a scam accusation here : https://bitcointalk.org/index.php?topic=5325714.msg56626251#msg56626251

It would be great if we know the actual situation on blocking the account. One more doubt is that do you close the account if the coins came from a mixer as per the image posted by the user it says that and i have not heard any situation where a gambling account is closed because they used mixers.
