The second thing is that I haven't read your entire thread at Project Avalon out of a lack of time and energy. I am the administrator here at The One Truth, I am one of the administrators at our sister forum Eye-Rise, I check in at Project Avalon several times a day ─ where, as you know, traffic is a lot busier than here ─ and then I also check in several times a day at the PCLinuxOS forum, and I am an assistant-moderator at the Manjaro Linux forum, where I provide lots of technical assistence. And on top of that, I'm also suffering from various health issues. So it's simply not feasible for me to read everything into detail, and I have to maintain a mental filter. I don't read any long threads on any other forum than The One Truth anymore.
Now, what I know of your situation at Project Avalon has already been said on this thread here, and so I have to go by that information in order to answer your question. Do I think it was fair? Well, Project Avalon is Bill Ryan's forum, and as such, he holds the prerogative to lay down the conditions people must live up to if they want to remain members at his forum. He has every right to demand that. As a Project Avalon member, you are a guest in Bill Ryan's living room, so to speak, and it is a guest's obligation to behave according to the rules of the house.
Did you violate those rules? Well, Bill and his moderators seem to think that you did, and not knowing all of the details of the situation, it is not for me to say whether their impressions of you were correct or not. But it's their house, and they felt that you didn't belong there, and that you were being an unproductive member. Personally I wouldn't have banned you per se ─ again: I don't know the exact circumstances and I can only go by the small amount of information I do have ─ because there is always the option of graceful retirement, which still allows the retired member to visit the forum and read all of the material in the public section ─ not in the members-only section anymore, of course.
Was there an influence from Bill on his members in this decision, or vice versa? Yes, most likely there was, but it won't have been deliberate. One never lives in a vacuum, and people interact with one another, and their opinions always weigh in, even if you don't accept them. For instance, someone could tell me something that I don't accept for true, but nevertheless, I will have heard or read their words, and I will have spent some computing cycles in my brain on whatever it is that they told me ─ whether true or false.
But has Bill yielded to the pressure from his members? No, I don't think so. Has Bill willfully rallied his members to gang up on you? No, I don't think so either. But have the members ganged up on you? Well, to a certain extent they have, yes. It's human nature, and the anonymizing aspect of communicating over the internet facilitates this gang culture. Project Avalon is certainly no exception in that regard, but it gets even worse if you look at things like Facebook, Twitter, Instagram and all those other "social media". At least the staff at Project Avalon are still intervening and they actively try calming people down via the back-channels. You don't get that on Facebook, Twitter and whatever else is there.
People are acting much more upon instinct than upon conscious thought ─ just as The Powers That Be™ want us to behave. And that's exactly why we're "sheeple". Most people don't even know themselves, but they'll always be quick to judge another. For the record, I'm not saying that this is what happened to you at Project Avalon, but it is a general observation on account of humanity from someone ─ me ─ who has never "fitted in" anywhere, and who has also been the victim of bullying and mob rule in his life.
Time heals (almost) all wounds. You are feeling hurt right now because you feel you've been treated unjustly. I can understand and appreciate that. But the situation is what it is, and there is little to nothing you can do to change it. The past is either way the past ─ it's all water under the bridge ─ and time is only moving forward in this reality. So try not to dwell on what lies behind you, but instead focus on what lies ahead. You're still young, and you have a whole lifetime ahead of you. So try looking at things in a positive light. Everything happens for a reason, even if we don't understand said reason.
