Is YOBIT scam? my account is freezed

Hello, all

I am a user of Yobit.
I have a big issue. my account is freezed suddenly even i didn't do anything
When i logged in it just appered "Your account is freezed. Access to some actions is limited.
But i don't understand because i just logged in and didn't press anything.

It already over 1weeks and even i sent ticket many times to support and Pm, there are never answer me yet.
But first one i got replying mail and i could see one link "0.001btc , say thanks"
It seems i have to press for paying 0.001btc to deal with? so i paid 0.0001btc.
I also answered the question.

its the replying mail.

You locked yourself by clicking at button "Freeze withdrawals from my account (I suspect hacking)" at Settings page.

For security check we must ask you some information before unlock.
Please describe in this ticket: approximate date of registration at Yobit and your last actions (deposits, withdrawals, orders, etc.)
with approximate amounts.

Say thanks
