If I understand it right, the moderator of the mastodon.world instance has blocked several posts by Hasnain Kazim, as Kazim reported yesterday on Facebook: https://www.facebook.com/661473263/posts/10163657720033264/
Kazim is a quite famous and successful book author in Germany and something between left, conservative and liberal. He was journalist for the most important German weekly news magazine Spiegel. https://en.wikipedia.org/wiki/Hasnain_Kazim?wprov=sfla1
Canceling his posts is stupid and certainly completely exaggerated. To me from the external perspective it seems that the moderator is abusing his power. He is damaging free and respectful discussion. Furthermore, when a famous person like Kazim reports those experiences to his broad audience, who do not understand the functioning of the fediverse, the moderator also damages Mastodon in general significantly, it seems to me.
What do you think about this case ?
People's first impression tends to color how they view something. Fair or not, the first Mastodon instance you join tends to affect your view of the software, and the Fediverse as a whole.
If people tell you to join a social media website, and you get treated poorly when you join, why would you want to stay on that website's social network?
