Re: Oh, now sites are responsible for what's posted on them?
I have to say I disagree with you on this.
To play devils advocate, (and to steal the excellent analogy of the bulletin board from Mr Cobb) what your proposing is that should a Church put up a bulletin board, they can either act as a platform and not be liable for what is put up on the board, but also not be allowed to remove that flyer for the Satanic Church just down the road; or they act as a publisher, where they can remove or ban anything they want from the board, but can be sued for spreading hate speech when they start posting anything from the Old Testament on the board, or if they are just too slow to react to one of the parishioners posting up a rant against Gay people or in support of the KKK.
Now, I'm pretty certain in the real world, most people would expect the church to be able to decide what is allowed to be posted on the church bulletin board and to remove anything they dont like. It would also be expected that they remove anything hate filled and illegal as well, although people would be inclined to give them a bit of time to notice the problem and remove it.
Now if the Church moves there bulleting board online, does that change anything? Same rules would apply, no? Maybe we might expect them to act faster than with the physical Church to remove the bad stuff, but other than that the same rules apply, no?
Now define why a social media company should be held to a different standard to the local church bulletin board? That way lies madness...
