first im going to say sorry ahead of time for my bad english skill and i hope most of you here can understand me.
firstly, from my own point of understanding and prospective, the only reason you are getting your account banned is because you have used a third party software or plug-in that modifies the game's data intentionally or unintentionally.there is something like a firewall in the game's client that detects abnormal activities on the game's server.it doesnt matter if it is done by you or your friend or if you logged on a friend's computer who has something illegal, you will be banned and no questions ask.
a permanet ban will not be undone, because there is no proof or evidence suggesting that you are not the one who caused it. we are not playing on a server paying 20$ a month and you are gonna understand that. if everybody on the server is using hacks or exploit, then it would be chaotic and soon the project will come to an end if no one on the elysium project team is doing anything about it.
i myself also got banned. because i am stupid enough to share my account with a real live friend who played on the original vanilla game with me back in 2004. he decide to mess around with my account because he is not not taking the private server seriously, he thought it would be ok to use something illegal on a private and no one is going to do anything about it and boomed!!! i got banned!!!
to those of you who decide to use hacks or share accounts with friend. just stop it!! the consequence will be harsh!! a few weeks or months of your hard works will be downed to the drain and one is gonna be listening your stories here.
elysium project is awesome. the devs are doing a great job keep the servers up and running. keep the good works up and let the server become a legend!!
good luck to the fellow players and best wishes to all of you people who is in the situation like myself. farewell
