Having a similar issue, added another user (family member) in the same country (in EU), now in liquidation only mode for over 2 weeks. Calling every other day and they keep promising to fix the issue (promise to call back as well while never doing it).
This seems to be a way to get rid of successful short sellers, next thing will be keeping only the losing traders to prop up the MM business and achieve even higher profit margins. It's the only possible reasoning I can see right now.
Why I don't just leave IB?
I programmed my systems using the IB API in good faith, thought it was a safe bet. Obviously I was wrong.
The guys who praise IB for actions like this will find themselves in a similar situation at some point, then it won't be so awesome.
Just found this thread.
Were you able to solve the problem?
