Yeah that's true. I think a lot do just want attention. Ignoring them is a good policy. But sometimes it reaches a point where it seems like authorities should be involved. John Barrowman once tweeted to some fans who were getting unruly that police can be involved and the network was concerned about Emily's safety so people with the show know that's an option which is good. Although I think to some degree Twitter needs to do better about cracking down on people too. Anyway maybe by the time the new season starts a lot of these haters will have finally gotten bored and moved on.
