  "I have stepped forward on a few other posts - I also had money stolen from my MtGox account (20.19 BTC)
I even reported it to MtGox with no reply (this report was made before it was announced that there was a security exploit found).
It has recently been revealed that MtGox did in fact have a vulnerability, and someone even showed them the exploit by using it to prove it was there. There are also a dozen or so of us that have had this happen. Yet, the owner claimed that he can see no evidence in his logs that our money was lost due to the exploit, and that he is not going to refund anybody for the BTC stolen from his (insecure) site.
I for one will never use MtGox again.  Its one thing to make a mistake and have such a simple exploit left open it happens. Its another thing to not own up to your responsibilities as a responsible business owner. Look at the number of trades on his market, look at his fee and do the math.  Bottom line is that he makes very good money from his userbase, and should be trivial to do the right thing for a few handfuls of users that lost modest amounts of bitcoins.  I don't know if it can be proven one way or another whether or not the withdrawn funds were via an exploit or not - but honestly, look at the evidence"

having been a victim of this security flaw myself, I dont see why, considering the mass amount of cash mtgox is pulling in right now. they don't reimburse the people who, in say the 24 hour or 48 hour window this scam occurred, and reported a trouble ticket to them in that time (seems all happened on the 15th 16th) even if from their own funds for gods sake... up to say "x" amount, but whatever... I guess that's why I don't run a business.
