We would prefer that posters bring their concerns about topics or individual posters' behavior to us in Private Messages rather than reporting them publicly in this topic.
It may be that the posts you are talking about were banned and you did not see it, were not banned because they were acceptable, or were not banned because they were not noticed. It is impossible to say without actually seeing them.

Innapropriate Posts & Banned Memes
- Thread Whining / Respect to Others. It's not that "Haters gonna hate" is a banned meme, it's that it's often used to be flippant and dismissive to other posters. If someone is trying to explain what they think about something, either treat them with respect or don't reply at all. So when you post "u mad", "deal with it", "haters gonna hate", "the GAF hivemind", "the usual suspects", "but GAF said x and now they're saying y!!!", "entitled whiners" or anything else that suggests that you don't care what other people think, you may be banned if it is taking away from discussion. This is getting to be a pretty big problem, and it's probably the single largest category of bans these days. If you don't want to discuss something, you don't need to post.
This also includes things like "weekend gaf", "sounds like a GameFAQs threads", "tl;dr", "cool story, bro", "Neat" and associated image macros, "who gives a shit", etc. This list is not exhaustive, and using variants of these statements such as "bold please" and "f*ck the haters" is not a good way to avoid getting banned, as the problem is the general message/intent of your post, not the specific words you are using. If you think a particular thread is lowering a quality of the forum, PM a moderator about it.
And while not specifically mentioned, this includes dismissive "defense force" posts. You were not treated unfairly.
