Run a quick SF update that includes bittrix so that this account may not be able to transfer any fund until the discussion ends and temporary SF is reversed.
That solution does not seem like a good one because the funds still end up in the @bittrix account. Then what happens to them. They stay frozen in the spammers account?
@glory7 your solution is to freeze more accounts?
Let's just try to stop a leaking bucket by adding more holes. The one and only solution is to release the accounts immediately before more damage is done.
