Much nicer runs the fact... Aggressors are not allowed to issue further demands during the same encounter after the trade vessel has complied,...
along with that... ..., a trade vessel can be destroyed if they refuse to stop after being asked to in the form of a proper demand.
which is insanely awesome, bc demanding the trader to halt his ship, done properly, accounts as demand, but after the trader complied and stopped, the "aggressors" are not allowed to issue further demands, say... ask for the money they stopped the trader for to begin with.
Just... awesome.
Call that one bad wording of a rule.
Good luck pirates. Have fun.
