Hmm. I guess its just a sign of the times. There is nothing that can't be hacked, and being a site that does what it does.... people had to have known the risk. Its a shame that so many lives were affected, but they didn't need to join such a site. I know that I couldn't possible consider doing such a thing.

I'm not taking it personally, but you are unfortunately completely oblivious.  You don't know what is going on in people's lives.  For example, perhaps a happy couple had an unfortunate incident where a man had cancer and is impotent or otherwise unable to function.  He gives his wife permission to have a subtle affair as long as he doesn't have to hear about it and none of the their friends and family know and embarass him.  This could be devastating and ruin his already challenged life.

Or in the specific example I gave where my girlfriend actually had an account on the site that her and her friend set up to see if a co-worker was on there as a joke.  If she hadn't told me about it and showed me long ago, I might suspect something if I found out after a leak.  It could ruin an otherwise wonderful relationship.

You don't know circumstance, you don't know peoples lives and you or no one else has a right to say that the people involved in this should know, want to know or anything else.  Me?  I'd want to know of course, but both you and this hacker are forcing your views on others, and this hacker has done it unlawfully to boot.  And he hasn't worried about any of the mistaken collateral damage he has done in the process.  Not to mention stolen emails and fake accounts/revenge accounts...

Essentially this is basically like convicting everyone of a crime without a trial. The evidence would indicate that many are guilty, but some may have just cause, some may be falsely accused, some may have other valid reasons. And some victims might rather not press charges, and that's their right. The kind of action this hacker has taken is blind, dictator-like, stupid and against human rights.

Exposing someone that was behaving badly is not a crime. The hacking was a crime but it's not against "human rights". He merely stole private info from website that's for people looking to cheat on their spouse and leaked it. In the same sense, cheating on a spouse is not a crime but the most the time, it's immoral especially since the majority of relationships are monogamous.

I'm damn sure not gonna take the side of the cheaters. 

Eeeerrr.... I'm afraid I'd have to agree with you that I do not know what is going on in the lives of 2 fictional familys you are imagining in your head.

Pretty much this.

But i had that thought since months, i think it's for the best

Having faith in this statement might just lead to disappointment.
