Ooh... it has to be !life by itself. You are using Partiko, and it's adding the line "Posted using Partiko Android" to your post. You'll have to find a way to edit your post so that only the single word !life appears.
You may have to use steemit.com to get the editing done if Partiko can't do it. And this might also be something for @lordnigel to look at.
Haha.. not to worry. I will use busy.org instead. Would be nice if I can use Partiko though. I am sure it's not a difficult change to make :)
