A lot of posts have cropped up lately by some disgruntled user reading something along these lines:
I see that you are a new user to Stack Overflow, I suggest you to stay away and use forums and other traditional websites/media instead of this decadent and vanity-driven “community”. Your questions and answers will only make the business of the lazy admins to grow and your work to contribute will not matter at all when one retarded mod or admin picks on you and starts censoring or suspending your account for no reason. Greetings.
They've been deleted, but it's a pain and a waste of database space and time. Could a rule be created where posts within, say, 10 words of this aren't even added? They would appear to be added to the user, but they wouldn't exist. That would stop it for at least a while.
