Using a bot is fine... as long as it actually works, but there needs to be some occasional manual checking. Making a post 75 characters long doesn't mean the post isn't spam, and can be abused in several ways to get around it like this and the Malin Keshar situation. That user should obviously be kicked off the campaign for making poor posts alone.
I looked at his recent posts and almost all of them are in chinese. I certainly can't judge the quality. It's cool to know that you speak Chinese tho, hillarious. For some reason I thought you had told me you were Candian (not that there aren't candians who speak chinese, but that's certainly not the stereotype).
