I personally found the 5th reply to the same comment thread a little repetitive. Unless there is anything more to add to the conversation a simple upvote/downvote on an already existing thread is probably enough. I don’t think I ever downvoted a post though, just because I sorted by top/hot.

The article does not mention, how will this be achieved technology wise? I don’t know of any universal way that a government might activate these features on a person’s phone. Unless network operators/phone manufacturers start installing backdoors. This does not bode well.
