It is against the rules to have guards that are aggressive
by default at a pcity entrance. This is among others to avoid
the effect of having unsuspecting players accidentally dying
to pcity guards.
It is *NOT* against the rules to have guards that are
aggressive against *specific* players, especially when the
players in question have been targetting the pcity or the
owner(s) of the pcity. A pcity owner has the right to defend
himself/herself - the goal must be to defend the pcity tho,
not to use the guards in active pkilling.
Since the guards in question are not aggressive by default,
and only target a handful of players who have issues with
the pcity owner, there is nothing for us to interfere about.
