OK, if it's not "anything goes", what would the new boundaries need to be?
I just lost a lengthy reply that I'm not about to retype even if I could remember it all. So here is a somewhat paraphrased version.
There should be multiple levels of moderation.
Level 1 occurs in the general forums. These are the forums everyone can see and the first thing that new members to the board will find. These forums are
strictly diving related. While spirited discussions will be encouraged, cursing name calling and the like will not. Violaters will have their posts pulled and will have the opportunity to make them compliant. If they fail to do so, then the post will be deleted and they will lose the
privelege of posting after 3 strikes.
If a thread spirals out of control, it should be locked with a Mod warning rather than just "disappearing." This will keep all of the "where did xxxxx thread go?" posts from popping up constantly.
When a new poster asks a question for the umpteenth time, a Mod should post search results for the question, redirect the OP to the results, then lock the thread. There is no reason to keep answering the questions that have already been answered when there is so much good info readily available. Users can click the "report post" button to alert Mods when a thread needs attention.
One thing we all need to keep in mind. Many of these posters may be on a message board for the first time. In spite of all the FAQ's, etc. many don't have a clue how to search or find relevant information. When everyone piles on them telling them to do a search, etc. many people are discouraged and put off.
This board now has 80k+ members, but the most users ever online at once was over 2 years ago.
Level 2 should be opt in areas of general discussion. These areas would include the general chat threads, humor, non diving related stuff etc. They would allow for more "mature" discussions and topics while still remaining respectful of the variety of cultures, genders, religions, etc. Once again, questionable posts would be pulled by Mods and the poster would have the opportunity to correct, or it would disappear and their privelages revoked.
Level 3 would be individual groups. Since most of these groups are a close, tight knit group of people, it would be mostly self-policed. Users would be warned when they opt in that moderation is minimal. Pretty much a "enter at your own risk."
Those that come here strictly for the diving aspect can engage in that conversation without fear of reprisal.
Those that want more can engage in that as well under a bit looser restrictions.
Of course this is all rather idealistic. Reality says nothing is quite this simple, but perhaps its a good place to start.
