If the error you get while trying to login says your account is at risk, and that you should reset your password, it simply means that someone that is unauthorized have tried to access your account and BC.games blocked your account to protect you as well as stop the hacker from getting into your account.
Now, the above is just my assumptions based on how you phrase your topic, I could be wrong, but a way to confirm if what i said above is right is  to try to change your password, if you are unable to, contact support and give them time to respond, and when I say give them time, I mean give them like two weeks to respond, if by two weeks , they don't respond, then I believe you are then free to become suspicious and also create a scam accusation and remember to include the evidences.
