Consider this...when we don't want ourselves looking bad, why do you think that is? Well, what's your thought process right now on the staff and how does that make you feel? Do you like how the staff handled it?
Let's put this in perspective...
You, in what really happened: "I don't like how the staff handled that...I don't like that staff member" And your current self "I'm leaving, and here's my big post as to why and various issues...I don't like the way staff always handles things."
Everyone else if he was unbanned: "That guy made a homemade video where he puts his hand on the bible and swears to god and gets unbanned for it? That's no fair. They must be religious and aren't treating users fairly because of it [insert rant here]."
We want to look good so users don't leave for how "bad" we are. Sadly, not everyone will agree with our decisions, no matter which ones we make, and honestly, this was the better decision. Not only did he not deserve to be unbanned, but unbanning him would have looked really bad in the eyes of pretty much everyone else and defamed the staff more than necessary.
Now that's not to say we're perfect or always make the right decisions. Some staff members have made decisions in the past that I do not particularly agree with. There have been times where the wrongdoings of staff make their way into the public...and this bothers me. We have good reasons for trying to hide these wrong doings - it's not because we want to look big and mighty like we never make mistakes and are the greatest people, no...we don't want users getting the wrong ideas and leaving. In some threads like these, I've seen users blame the whole staff for these issues when in reality it was a single mod making one mistake. Sadly, the mistake of one mod can make some other users really afraid of being banned falsely or otherwise they'll leave for reasons like a "bad staff"...the thing that bothers me most about this is that these users don't feel like they can just sit down and play a game. They are in constant worry of being banned...I don't like that.
This is why we as staff tell people they'll never be falsely banned and have nothing to worry about, as if we were "perfect". It's true, the chances of a false ban happening aren't really that great, but when they do happen, of course the falsely banned user will be upset and likely to want to tell the world. The threads you see on falsely banned users are from the few who probably were, it is really rare. (Unless of course they were hacking, sometimes users who were hacking make a thread anyway, but occasionally a false ban will happen from time to time, I admit.)
We tell people to have nothing to worry about to make their MCSG experience a fun one. We want you guys to have a fun time, not in constant worry of false bans. Worrying about them won't stop them from happening, and the chances are so low anyway...
The other statements you said we made also have good reasoning: We assure users we looked over the evidence many times to make sure they understand we actually care about the issue and didn't glance at it and make a hasty decision. We also tell people we know what we are doing and are experienced to assure them that we've been here long enough to tell the difference between hacks and lag, etc...we aren't bragging or being egotistical or anything, we are simply trying to put you in the state of mind that there is nothing to worry about to avoid chaos and so you guys can have your fun.
Sadly, the noobs are something that must be ignored. "/chat off" is a good command for this.
If you see people harassing people, being rude, etc...feel free to report them. Sadly, we can't do much about other annoyances like bacca's being bacca's. You'll have to put up with that...be thankful the forum the community is still nice for now. Sadly, the community cannot be fully fixed on servers this big, it's just not possible. You'll just have to ignore them, sadly. :/
I'd put a TL;DR here, but my post is so all over the place that I won't bother.
I don't mean to offend you in any way, I'm just trying to clarify a few things and give some tips.
I had to triple post to fit that all...wat. I know most of it was quotes, but still...I just made the longest reply in this forums history, beating the last one by 20000 characters. >.>
Edit: Seems some of my revisions on this post, like a paragraph or two, isn't here anymore. I must have lost it in all the copy pasting I did.
Wasn't super important anyway, no big deal.
