Re: What do you consider acceptable packet / session modification for a network operator?

So the tl;dr I'm getting from this is that - I don't think anyone considers this 'acceptable' for an ISP - Everyone knows that AT&T does it anyway I haven't found any documentation on how or why AT&T is actually doing this, so it's all either very old or they've scrubbed it from the internet (I know they deleted their whole forums, and it seems like some of the discussion was formerly there)
