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 ?
Ah thank you, this is a crucial piece of info that was needed to more properly understand how to interpret the OP. This post would have been better written to not assume that we the reader already knew all of that, but regardless, thank you for filling that in.
