If a bankruptcy is filed and you had $ or BTC at bitfloor, you should be included on the list of creditors, and you'll get periodic mailings about the progress of the matter.
Now we are getting to the really interesting stuff. If BitFloor does not have any information on how to contact you, how will you get periodic mailings?
If some other legal action is filed, there's a pretty good chance you'll be included as a party, which would mean you'll get copies of filings,
See my question above.
BitFloor has no ID requirement for BTC withdrawals.
I'd just like to point out the importance of Bitfloor consulting an insolvency specialist and not a general lawyer. You need someone who'll advise you on all of the legal options available and their pros and cons.
