The only difference here is that the mods don't come right out with the "or else" in writing, the attitude is still the same and you've been a member here long enough to see that for yourself. Maybe the moderators wouldn't have such a "tough job" as you put is if there were clearly defined rules and guidelines for them to follow in moderating as opposed to the way it is right now with everybody doing whatever they please. One thing for certain, the postings about over zealous moderating that are a recurring theme here would not be quite so frequent.
As I've stated numerous times before I know from personal experience as a moderator on a worldwide site, moderating a forum in a country with a population over double that of the USA, I know the task is not easy. That is not the point being argued here. The point is that there is a complete lack of direction for the moderators and this acts to the detriment of the membership in general. Clear rules for the members to follow and equally clear rules regarding moderation would lead to universal and fair application of those rules.
When a posting does not violate any of the rules that already exist, when it expresses an opinion or mentions a topic and gets deleted simply because somebody doesn't want to hear that opinion; or in their abundant wisdom feel the issue isn't important enough to "waste" forum space and that action is taken arbitrarily and with absolutely no recourse it is patently wrong, privately owned forum or not. Since when do we as members all have to share the same opinion as the forum administrators and moderators? I'd hate to see nothing but a bunch of xerox copies of certain members or moderators filling the forums.
If you don't believe what I'm saying is true then just post a thread that puts down Microsoft Windows 7 or 8, criticizes something about Flightsim.com and see for yourself just how fast you get shut down. Maybe you're lucky you only have posted 63 topics... hardly enough to ruffle any feathers yet. Just wait it will happen, I'm sure. Perhaps when it does then you will remember the people who stepped up and tried to do something about the situation. Maybe you will also remember the American take-off on an old quote from WWII
First they came for the socialists,
and I didn't speak out because I wasn't a socialist.
Then they came for the trade unionists,
and I didn't speak out because I wasn't a trade unionist.
Then they came for the Jews,
and I didn't speak out because I wasn't a Jew.
Then they came for me,
and there was no one left to speak for me.
