Great reply Terrie!
One more point I'd like to bring up: The Staff work really really hard to do everything possible to resolve situations and issues BEFORE there are any bannings. We want everyone to be a part of this community if they are willing to be calm, friendly, and helpful.
Unfortunately some people, either knowingly or otherwise, post their opinions in a very abrupt and sometimes offensive manner. We usually Private Message these people multiple times with warnings, and if they still don't adhere to our rules they are issued a ban to the extent of the violation, as Terrie mentioned.
If you haven't received any "reprimands" or "warnings" publicly or via PM's from a Moderator asking you to stop doing something then you're not even close to being banned.
Also, if a post is edited, or removed entirely from a moderator, that's usually a REALLY good hint that the members shouldn't have posted it publicly.
