Regardless, my question was: What is the reason for one-word "BULLSHIT!!!" posts being acceptable, while one-word "LMFAO!!!" posts are deleted for being off topic?
I received the answer from admin: the first is a decidedly on-topic response to the content of a post, while the second is a personal attack.
My followup question would have been, why is "HORSESHIT!!!" deleted, while "BULLSHIT!!!" is fine. It's obvious now; making an association between what a person is saying and the excrement of a bull is clearly on topic and speaking only to the content of a post. But the excrement of a horse is an entirely different story.
