I didn't mean it in the sense that you could have legal action taken against you, but rather than you simply ban people who offend somebody else.
I get the sense that the idea would basically end up as morality police for the internet, which I am completely against.
As I said earlier in the thread, even if the intention is to simply stop legitimate harassment all I can see as a result of it is people turning around and harassing anybody who says anything the slightest bit offensive. It becomes a witch hunt, and those always end badly.
That's why the moderators should be chosen wisely in order not to have power abuse. What is authority but rational leaders who have learned to use their power without abusing it? Nothing is guaranteed, That's for sure, Bu hypothetically speaking if this could be possible, At least maybe give it a try and apply trial mode for 2 weeks on particular sites and then see the results. If positive, Then it should continue, If negative, Then it should not. Also, Internet Police Officers would be monitored by supervisors, They don't act as they please, They follow protocol. For example, If a fight is starting then the officer should intervene and advise them to the righteous course according to the protocol. If they don't listen, Then you start thinking of alternatives. Warning the user, Locking the thread, ... etc.
