Matt Dioguardi owns a Facebook group with around 5000 members. The membership believes it's an open discussion forum with relaxed rules (just post all you want that's related to Popper "in some manner"), because that's what it publicly states, in writing.
However, I was banned because I didn't like some of Matt's friends' comments and blocked them on Facebook to stop seeing their messages. I don't need toxic people in my life.
I would never dream of banning someone from the Fallible Ideas forum because they set up a mail rule to block posts by my friends Justin and Alan. Some of Matt's friends, like Justin and Alan, were moderators – so what?
Prior to that I had some posts blocked for reasons like mentioning Ayn Rand (in addition to Popper) or mentioning parenting and education (from a Popperian perspective, and in addition to talking about how to spread Critical Rationalist ideas). Discussing the moderation had been unproductive (they refused to answer clarifying questions about the policies or update the stated rules to the actual rules). Some of the forum discussions had also been unproductive (e.g. I repeatedly asked some flamers to stop harassing me, and they did the passive-aggressive version of telling me to go fuck myself – then redoubled their efforts to harrass me). I didn't flame anyone.
So I decided it was time to stop engaging with the toxic people. I knew I was at risk of being banned if I did some further action that wasn't appreciated and there was no problem-solving discussion to address it. I decided to risk this because I thought talking with the toxic people wouldn't solve problems and could actually cause problems. But they wouldn't just leave me alone. For my decision to refocus on productive discussion, and ignore everything else, I was banned. (Dioguardi stated the reason for the ban, it's not speculation.)
Some of them clearly didn't like me (e.g. one of the moderators was also one of the repeat flamers) and wanted an excuse to get rid of me. But what kind of excuse is this? Nothing was wrong with anything I posted, and they banned me anyway!
Update: They also banned anyone from posting a link to anything I wrote.
