In particular, it’s just lazy to escalate to a permaban right away. Even if they have a rule against reposts, removing a post along with a warning not to do it again is sufficient to educate the vast majority of people there who may not have seen the rule and only did it for the first time.
But that would take a few extra minutes, I suppose, to check someone’s post history and see if they are a serial rule breaker. Much easier to just wield the ban-hammer then ignore.
I bet if another storm heads toward Louisiana they’ll have a vote faster than you can say "Fucking Hypocrite!’
