Just read that a flagship non-Mastodon instance blocked at least one major server (the biggest UK #Mastodon instance) preventing their users interacting and exchanging with each other. Not sure how this walled bubble approach fits in with the enthusiastic attempts to place such instance as some kind of mainstream alternative to #Mastodon. I am off for good, I like to make my own decisions on a server with mature and non-arbitrary admin policies. @fediversenews
