Hi,
Today, I was playing Muli-BTC as usual and then after some time my account has been locked.
I have only one account, I was not using any VPN and I was not using any bots.
I'm highroller and premium user since the beginning of this program. I'm active FBC user.
As normal I was just using built-in feature "auto-bet" and that's all.
In my history I made a lot of deposits and withdrawals and I've never had a problem.
Now when I'm logged in, I have just a blank page with a message:
"Your account is locked. Please contact @hallohap_1 on telegram or
fellowyun@proton.me email. Failure to comply will result to a lost of funds."
After some time, e-mail address has changed and at present it is:
Your account is locked. Please contact @hallohap_1 on telegram or
bellera12@proton.me email. Failure to comply will result to a lost of funds

That's very disturbing.
I've just got a response from this email.
"Your browser is hacked. Send 0.5 btc to bc1qhrdvuxrealra5xm7qsu9tyh06k3frcrzuvsms7 to unlock it. Why trust me? I cant withdraw your money because it needs otp and email. Ill wait 1hr before I drain it"

What the heck?
