I´m not sure what you mean by "accidental rule breaking", because most common rule breaking is quite intentional (F1 to get out of unwanted interaction despite server gives all the time warning to not do that, swearing, threatening with sanctions...). Though as far as I noticed permabans are issued only for serious violations against game environment like hacking/fidling with files, or against community as whole. And by the way, I seriously doubt there is one permaban per week, from what you got that?
Also, current admin policy is a lot more friendly than it used to be towards typical "newbie violations" - instead of silently simply deleting ships or removing equipment, violators are often moved to Bastille what forces them to look to the forums and rules, and once they reply to sanction thread and explain they understand what they did wrong, they are usually released.
