You are right; deleting a post is a game so you cannot take any action.I would name names but I'm afraid that someone would delete this post or suspend me. It's frustrating because I feel like I'm not allowed to ever defend myself even in the most non-aggressive way without a p;articular mod deleting my post, sending me a warning or suspending me. I can't even count how many times I will post something serious and someone will come along and make a snarky comment that is uncalled for or completely unhelpful or slight personal attack and if I even say anything back (often in the same manner) I get punished. I love MacRumors but it's like we are children and are not able to stand up for ourselves.
Sometime I don't even remember which post has been deleted.
What I have noticed is that if a post has received many POSITIVE reactions and it is not so aligned to their marketing department it will be much more scrutinized by somebody just to find a good reason to cancel it.
