I was one of those instructors. I went through different phases of reaction to ScubaBoard back then. Sometimes I just didn't mention its existence and hoped they wouldn't find it. Sometimes I mentioned it but gave a major warning about it. This continued even after I was a member of the staff. I was an active member of the community, but I really didn't want my students to know about it.As late as 2004 I saw training agencies with notices at DEMA decrying the interwebs and encouraging instructors to avoid ScubaBoard.
I described the problem in my first post in this thread-- the 5-6 POV warriors and some of their "wanabes." When a new diver came to ScubaBoard and posted something--anything--in the New Divers forum, he or she would be assaulted with posts going on and on about how their instruction and instructor sucked. If someone asked a question in that forum or the Basic Scuba forum, there would follow a series of posts that essentially said, "If you have to ask such a stupid question, that shows what utterly crap instruction you had." Even as a staff member, I did not want my students to visit ScubaBoard because I knew the number one thing they would learn there that they were lucky to be alive after getting instruction from a piece of crap like me.
I said this during a moderator discussion about this problem back then, and we enacted changes that old timers will remember. We made the New Divers and Basic forums "green zones," places where those kinds of attacks were not allowed, places where people could ask any question without being attacked for not knowing the answer already. We outlawed agency bashing, which is the practice of making blind, mindless, unfounded attacks on any agency, to be distinguished from factual descriptions and discussions on specific agencies practices and policies. We made the aforementioned changes to the A & I forum. Those changes were very effective, and ScubaBoard stopped being a place that was so obviously hostile to modern open water instruction. It became safe to suggest it as a place where new divers could go to continue their growth.
Yes, the attitude toward ScubaBoard has changed since those days, but that is to a large extent because ScubaBoard recognized that it had a problem and took steps to fix it.
