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 ?
This is not an objective fact but an opinion (whether well-substantiated or not I cannot tell). I am not clicking on a Facebook link to learn more, so thank you for adding some additional context here.
There is also a [email protected] community that will certainly agree with you that anything done by a .world community moderator is by definition wrong.
As for myself I have no opinion on this currently, but only questions like banning one person does not make a place authoritarian/fascist but a pattern of such events would. All that this post says though is a complaint about the one person - again, whether justified or not I have no idea, as other commenters here are likewise saying, we simply do not currently have the facts to be able to judge properly.
