are you saying its good practice to out people's security vulnerabilities without contacting them first?
I can appreciate the theoretical outlook you're coming from. Here's what happens when you try to contact idiots first: http://www.google.com/search?q=bitdaytrade+reddit
Look through the posts there, you have actually competent people trying to talk the guy into safety and some strutting imbecile puffing a lot of smoke about the imaginary experts he's hired, the imaginary expertise he has and on and on.
Thus I can certainly appreciate the practical outlook of warning the community first. I guess in the end it all comes down to a judgement call. Did the OP think the failed site is administered by sane people likely to take appropiate measures in a timely and effective manner, or did the OP think the failed site is a scam run by patent liars (Vleisides, Zerlan etc)?
Yes I certainly agree its a tough call between protecting the innocent, and tarring and feathering incompetent admins into taking action.
I think the way that guy did it was better, "you register, ill show you I can get your pw hash" a good mix of publicly outing them, without actually posting the vulnerability itself letter by letter.
(also sorry for MPOE typo on my previous post... autocorrect :/ )
Maybe my opinion is coloured by me having an outstanding order with BFL, but I'm still giving them the benefit of the doubt, in that I understand what they are doing is hard. Maybe that makes me a sucker, time will tell, and if I do lose that money well that will be another one to chalk up to experience. I'm not so naive as to think that every btc 'investment' I make is gonna pay out. Anyway I think thats a different subject!
Me I'd have contacted them at first, and *then* when they didn't do anything start escalating.
