I've also just read this thread, and I totally disagree with you. This is not about embarassing someone without reason. If someone manipulates members of a community, thus harming the community, this person should be expelled, and for that, those manipulations should be made public. Besides, threatening someone to hack their computer is a criminal offence (at least where I live) and should not be tolerated. It's not about liking or disliking someone.
In a witch hunt, the accused doesn't get a chance to properly defend him/herself. As several forum members have stated, they're still willing to listen and waiting for a statement.
The victims of any such manipulations have my respect. It certainly takes courage to go public with those things.
