Yes! Shouldn't we also be aware that an edit was made? If this is already the case, then I may have missed it, but what's to say as a joke someone switches from a thoughtful post to an nsfw or similar post that you would not wish to have your name associated with and reputation tarnished. I'm not entirely sure how the blockchain handles that or if you simply have to go back and remove comments and remove your upvote. This is even more true of comments. Once someone comments on your comment you cannot completely delete your comment, only change it. And someone could completely change what they have said to troll someone else and make them look bad. As far as I know, edits do not show up in the blockchain like on steemd.com correct me if I am wrong.
