What admin has ever officially stated that if you have a post that is under 5 words then it is declared a shit post? Are you sure you know what an opinion is? Cause there can be many useful posts that are under 5 words.

Like in my opinion, a useless post is something that does not have anything to do with the conversation at hand. You can obviously contribute to a conversation in less than 5 words if you really wanted to.

Edit
Even though you may think Tochukwu shit posted then fine, but in my opinion he put in a one word post that was supposed to obviously initiate a response. Which means that he was actively trying to contribute to the conversation by moving it forward.
Als in my opinion you should stop yelling at people for shit posting when you do it all of the time, its not really fair.
