We've been over this a number of times. What it is is that you freak out every time someone starts doing this to you and post a rant on the forums. This is a response that many denizens of the internet (called trolls) find endlessly amusing. Every time this happens it results in the same thing. They rate you one until you get upset, you freak out on the forum, and you reward them for it by being their amusement.
Best way to stop it is to not acknowledge it.
