What are those features? I've never used iMessage but my ultimate point is that iMessage isn't enabling bullying, it just happens to be the platform these kids are currently using. The same bullying tactics have been possible since long before the iPhone existed.

So far semi-extrinsic provided a list of features they think is uniquely enabling bullying in iMessage but I've just established those features are actually commonly available to everyone, so what other features does iMessage have that uniquely makes it enable bullying compared to MMS?
