Welcome to the Fediverse where mods and admins alike will ban you for no reason whatsoever
(multiverse.soulism.net)
I've earned a lifelong shadowban on the largest Mastodon instance just because I doubted a political paper (which later turned out to be as unsubstantial as I said it would be). And there's no way to contact support as support only answers to actual members, not people from a different instance. So, ever since, whenever I reply to someone from there, they need to approve my comment before anyone else from that instance can see it. Same for when I want to follow someone new from there. It's ridiculous.
