The /sell command has been permanently disabled on the main server. Announcement coming next week. We had a good run /sell hand on main. This is to prevent destruction of towns and hoarding money on forum bank due to current rumors Announcement soon. (And yes there are some who can destroy full vaults and hoard 100-200+ million, won't happen.)
You can still make money using SkyBlock's /isr command and the VMR theme. Main information will come within a week or so. Sorry no leaks, and no use listening to people's rumors, I can assure you I'm the only one who knows what the announcement is.
