Just to add to the "tag" thing. If someone is going to flag you for this, they would most likely remove their flag if you were, in fact, wrong and removed the tag. Or explain why you added the tag and they may agree and remove the flag.
I get that it is frustrating, but it's the only tool available right now to stop people who are abusing the system. Since we don't have a way to really search through steemit yet, the tags are all we have to find the content we want to read about. If we want to read about #bitcoin and someone posts a picture of their cat using the tag #bitcoin because it is a popular tag, that is surely going to annoy some people and they will flag it. It's not the best system but it's really all there is right now.
