So you think that clodminr that sent every week 200-300 btc to its users it is selling their usernames and emails for only 1 btc. All this to have this big amount of 1 btc and to make the story seems real?
Nobody would keep passwords in plain text in their database if they have good intentions.
I don't see problems here. They can enter in every account even without the passwords. The passwords maybe serve for various verifications with the users. You are telling that they have planed the story of the hacking and the selling of passwords since the beginning?
