I was banned years ago (Jem_Oz) because I defended a new forum member who asked a simple question and copped a shockingly rude response. I called out the rude responder (respectfully I might add) without realising it was none other than Charlie. The ban was swift and permanent.
I learned a tremendous amount from that forum. I have a bulging folder of screenshots that I've referred to many times over the years. It could be a bit elitist at times - a handful of people acting like they ran the place and the rest of us were merely visitors - which happens with lots of online forums.
My biggest beef though was a small handful of prolific contributors who seemed to be driven by simply commenting on EVERYTHING and being the guru on everything, without realising that they constantly flip flopped on their beliefs and health practices. They'd take a new supplement, feel amazing, make a post about how that supplement had changed their life, and then a week later, make a new post saying everyone needs to stay away from said supplement, it's toxic and will tank your health. Just endless versions of that, without the faintest capacity for self-reflection, such that so many threads got hijacked by these flip flopping know-it-alls.
