It's your 2nd ban for leeching. Being banned for 1 day isn't really that long.
You're not that much of a new player, so you should know being inactive for longer is not allowed. At the time when I banned you, you were also kind-of hiding on a tower; linked with previous kicks, there's no way for an unban.
If you have to go afk for a short time, for whatever reasons, you can either tell admins with the "i"-key chat, so they wont kick you after a limited time, or just leave the server.
You were afk for 1 whole round, approximately 5-8 mins, that's too long without telling.
