I received a ban a couple of months ago. In my opinion, it is really up to the mood of the moderator. If they want to ban you...they will warn you of course...but then if you post anything at all after that, it gets hyperfocused on by them...because well...they are in the mood to ban you.
This forum seems pretty much like all human-moderated forums. The playing field is not level, and certain members receive more perks and lattitude. That's true of all such forums of course. These members will make snide remarks, and if you respond in kind...you will get banned...if the mod wants to ban you. It's all very juvenile and click-ish like junior high school (or perhaps prison), but that's a forum for ya.
The internet is almost identical to a video game. Sometimes you just want to shoot what you see on the screen. The more you shoot, the more points you get. Personally I outgrew video games by about age 15. But these days, it seems there is a generation who is so narcissistic that they will never grow up. And they expect you to be happy about that, and to bow to their whims and their willful ignorance of the people and world around them. I guess that's why so many college grads these days aren't getting hired to do the type of work they expect. They feel so entitled that they will never learn the meaning of respect, and are happy to tap away at their iPhones even during a job interview...Why? Well, it's because they are the most important generation in the history of the world. Haven't you heard? That's how their parents and the current culture raised them. It's time for change.
