I've been searching around for a while, and haven't found a definitive answer on this.
I've been on a server before (rented through I believe Nitrado?) where they had an infinite upload limit when it came to items. You could upload items to your heart's content via a terminal, drop, or transmitter. I can't for the life of me figure out how to do it though on my cluster. We can rule out mods because S+ was the only one.
Unfortunately, I'm not in contact with anyone from that server or else I could just ask them how they were able to perform this sorcery, so any insigh
