I'm afraid the result will be the same as file sharing. There was Napster which was killed by labels, then Kazza which was 10x harder to kill, then torrents which are 100x harder to kill. If they manage to kill it something new will be there.

The solution is quite simple: if you're not willing to ignore trolls, don't use this kind of social network.

You should NOT drag your family into the business, not even if PR person will tell you that it increases your brand equity.
