I am on the moderation team at Treehouse. Marcan has not violated any of our community guidelines and he categorically was not suspended from our Fediverse instance. He chose to delete his own account.
Feels like a problem with the dynamic/partial JS content loading.
(Apologies for the confusion, there's no indication that made me suspect a bug... and I hadn't at that point seen anything about him deleting his own account yet.)
