I suggest you read this: https://steemit.com/steemit/@thecryptofiend/the-steemit-etiquette-guide-illustrated-by-klye. The appropriate paragraph would be the following "If your post does not directly relate to a particular tag you shouldn't be using it. A post about trumpets that just happens to have a photo of a trumpet in it should not be tagged with "photography", similarly a post discussing DASH is fine in "cryptocurrency" but should not be tagged with "ethereum". Tag spamming annoys people and rather than getting you extra upvotes is likely to get you a flag."
Don't use popular tags that don't apply. In this case it is steemit. Please use proper etiquette.
