I do not know if it's a permanent ban, but that user coindolnews was famous for posting BS that always got deleted, IIRC, that user most times gets the whole of their posts deleted by the moderator, prolly mods have decided to ban, nuke or tem ban that user. See this thread complaining about coindolnews' BS posting activities: https://bitcointalk.org/index.php?topic=5253793.msg54573653#msg54573653
