Changes to “Dispute a ban”
Prior to now, if a player had been banned before, they were permanently banned, with a chance to appeal 6 months later...
As of today (as of this post) If you have been banned more than 3 months prior, it does not mean your ban will be automatically denied.
Going forward we’ll be looking at bans in a new way, this is due to people that made mistakes on their first day being totally removed from the community for breaking a rule a year later...
This doesn’t mean that you can now break a rule every 3 months, previous bans will be looked at, so if you’re banned for VDMing people intentionally, and do it again 3 months later, chances are you’ll be on the next ship off the island.
So in simple, been banned before and just got banned? You don’t need to write a 400 page leaving post, but make a nice, honest, accurate unban appeal instead.
If you have been perm banned however, you must wait 6 months to make an appeal in the 'permanent ban appeal' section.
Does this answer your question?
