I moved this to the correct category and I want to inform you that it was me who banned you, bloons3 as senior admin only authorized the permaban.
The permaban is standard procedure in cases where the offending party has disconnected after performing the rules infraction in order to open a dialogue through an appeal.
I am going to break this down for you:
Planting Kudzu on the station as a non-antag is always self-antagging and griefing, it will damage the station, possibly kill crew, and be a very huge nuisance that will very likely ruin the entire round. Which in this case, it literally did since it covered cargo which is a critical department during a clock cult round.
Secondly, you planted the Kudzu in maintenance near arrivals, which completely ruined the chances for any new player to join the round as they could not feasibly survive after leaving the arrivals shuttle.
Thirdly, this was a clock cult round, meaning the shuttle never departed from the station, this was announced by the AI in the actual shuttle call announcement and again later in another announcement. The round actually ended much much later, almost an hour after you planted the first seed.
Fourthly, while EORG (End Of Round Grief) is allowed and even encouraged on this server, doing such before the round actually ends (and credits start rolling), is strictly forbidden and is classed as regular griefing.
Logs for added clarity
[2020-08-29 01:25:45.170] GAME: Halinder/(McAstermentanimoe) has called the shuttle.
[2020-08-29 01:25:45.171] GAME: Shuttle call reason: Meteors and clockwork cult. Telecomms hit (general server, so your department comms should be fine) hit. Armory hit. Bunch of other places too. Do note: the shuttle won’t leave because the clockwork cult can hold us here, well, FOREVER, but this is a good way to announce things are wrong. Maybe Central Command will even send help.

I will of course not let a permaban stick for what seems to be a lack of knowledge from your part.
But I do hope you take the time to read through the rules properly and understand that what you did was some pretty hardcore griefing and indirectly lead to the cult winning the round.
