First of all, nobody can know if it was meant for someone, or everyone or just a random remark.
Maybe it's not the worst language, but I'd say it's definetely insulting to people if they're told to 'eat shit'.
Besides that, land reserving, even in remote spaces of the map and when not directly blocking someone, is against the rules.
Your ban will expire at 17:37 European Time (Amsterdam, Paris, Berlin) at the 23rd (so in just under 18 hours)
Because of the short timespan of the ban and considering how much time there's left, I will not lift the ban now, but you'll have to wait till it runs out tomorrow.
But it's good you atleast recognize what happened and that you're promising better behaviour
