I don't know davout, but have met his partner boussac once.

My best guess is that they are NOT crooks, but they use exceedingly poor judgement when it comes to customer service and other aspects of running a business.  In particular, they are sensitive and immature and any perceived slight will set them off on a vindictive and unproductive campaign of insults.  A proficient support wing of any functional company can and will let such things roll off of their backs.

For my part, I will not trust them until they make a good faith effort to publicly document the investigation of the Instawallet theft, and produce a credible and verifiable accounting of the financial details associated with it.  Esp, how the unclaimed funds were used.  I would hazard a guess that most of the unclaimed funds (from tiny balances in people's wallets) were absorbed with their acqusition of Instawallet from it's original developer, but I am not aware of the business details that were associated with that event.

I would expect that you'll get you/they will get your account stuff squared away unless you are a blatant criminal and they can demonstrate it.

My personal view is that the amount of value to trust to ANY service provider in Bitcoinland is well below the amount that would be worth taking to the justice system if monetary calculus is all that is involved.  Dunno where your loss (temporary or not) falls.
