Lets look at Friendster from a less foggier lense, its an attempt in the right direction. Use it or don't use it.
Public ridicule, denunciation and mobbing works somewhat, better in countries with more societal coherence then the US, not that I'm a big fan of that, quite the opposite. In your case though, I think you shouldn't get any positive attention for anything you say besides "sorry what I did, let me help undo the harm".
