I don't usually block people so let me explain what happened. This guy has consistently caused problems for me and my experience on the Fediverse for the past year or two. Almost always, he would enter into threads or responded to reply posts I had made, then make completely off-topic posts that were usually about himself, rather anything that followed the flow and logic of a conversation. Sometimes, he would enter a thread that one needed to take with seriousness and sobriety, and ruin that seriousness, just to talk about irrelevant things, mostly about himself. More so, he would bring in people who didn't know better about the original topics, then egg those people on to spam the thread until the people who were originally talking leave and mute the conservation. This is a kind spamming, which I will block. It's not courteous nor respectful to other users. Deliberate making threads and conversations off-topic has always been wrong and selfish, and the failure for online communities to enforce that unspoken nor the nature of microblogging social media has never made it acceptable. But that is not the only problem. He has abused other users who are my mutuals. Sometimes telling them to "kill themselves". My mutuals may ignore that or have reconciled with this user, but I'm not going to because he refuses to change and learn self-control. I wish blocking properly worked and was stronger on the Fediverse and on Poast, but this is the best I can do to keep a guy like this >Blah, blah, blah! Why are justifying yourself and writing words, words, words doing so? Because I've said I don't block people unless certain criteria were met and have the autistic need to explain how this guy met those criteria. I don't want people thinking that I'm just mad all of the sudden and, in a spur of moment, decided to block him.
