They always come with this kind of argument “Why you did not plot all?” and “The one who claimes free space did nothing wrong, because it was free space and everyone can plot it.”
Thats so lame arguments.
Because these people who argue like this always forget, that the one who do this kind of “griefing” just do it, to destroy other gamers fun.
But to be honest, even we can’t do anything against it, and even it is in the frame of rules and in this kind allowed, it doesn’t make it better.
It is a bad behaviour just to put your own ass into someones settlement, and act unsocial like hell, just because you can.
There is a huge difference to do it in a obvisious project compared to a free town.
And even then, just to ignore all kind of town sense/rules/theme and not to be able to find at least a compromise with other townmember, makes the culprit an asshole.
