freitasm:MikeB4: I believe breaking into sites like this or any web site and releasing the information is wrong. As for the purposes of the site that is purely up to those who use the service.
Well said.
Well I possibly disagree with you both here. Whistle-blowing is legitimate and morally acceptable IMO - in the right circumstances it can justify the means.
Determining what those "right circumstances" should be is the problem. I mean really - the AM leak/hack is big world news, and there's a huge ensuing debate/argument over the morality of infidelity. I doubt that debate would have any impact at all on deterring somebody inclined to want to go and have a bit on the side - at best they might need to get a bit more sneaky about it. It's clearly not the right circumstances, there's no "common good" justification at all, the penalty some may suffer vastly outweighs the crime.
