You left out a couple of important points here Steerpike;
The cafe is loaded with a right-wing "religious" sense of prejudice and those that refuse to play by their rules will be quickly dumped and ultimately, banned for life. The irony being that the majority of Bizarrists & Mentalists that actually know their stuff, represent the bulk of those kicked off the forum, in that we tend to not play by the rules and call a spade a spade. And understand that most of the "big names" on that forum are there for one reason only; to sell product! They set time aside that allows all the wannabes to rub elbows with them on line so you will think them super swell human beings and thus, you're willing to throw money at them. I know of at least two who've deliberately pushed the edge of things just to see what they could get away with that others couldn't, their celebrity protecting them (if you look closely at the nose of the site's owner, you'll see lots of brown crusty looking stuff because of how far he pushes his nose up the hindside of such personalities).
There is no such thing as "freedom of speech" on the Cafe and because there are 101 different "members of management" each working form his/her own rule book, it's very easy to get get banned or given "demerits" based on personality clashes and related politics.
There is one other unfortunate truth when it comes to the Cafe environment -- its viral!
Take a look around at the sites you patronize right now and enjoy and watch how they slowly start to turn green over the next couple of years; they get cliquish, top heavy with management as well as the "home town hero" type of issues in which you have a couple of noted members that become "stars' or, as one of my older VISIONS columns calls them "E-Leberites" (forum celebrities). Some of them even getting their own sub-forums to discuss their own products as well as ill-due clout (as in "not earned" influence).
So think long and hard about why you come to any forum and what you want to get from it. More Importantly, think about what you can give to it in order to prevent it from becoming another Magic Cafe.
