Accident? yes
Ban justified? Also yes considering how long it took to rejoin. Really that's just on you
If the ban lasts an extra official because admins didn't bother to come to a conclusion for 5 days then that's bs though and I'd appeal to shorten the ban by 5 days

Perhaps a better metaphor is causing a car accident. It not being intentional doesn't mean you didn't make mistakes. And it'd be understandable to lose your driver's license/fine/whatever if it's concluded your actions were out of line
