Considering the actual definition of the word.. My scenarios and commonality assessment fit my assertion.
1.
a blustering, quarrelsome, overbearing person who habitually badgers and intimidates smaller or weaker people.
That is verbatim the Dictionary Definition of a bully.
So those three things I mentioned particularly more than one player vs a smaller (weaker player) or Very large say level 100 harassing a little level 30 with three to four attacks a day though only being able to raid for resources once a week to begin with, Just to show they are bigger than the little beginner is . Or let me take all the fiefs in your area and not let you have the opportunity to siege one because they all belong to me though I can only pull resources off of three of them. and should you hit one, well then I'm gonna attack your entire league, and wipe you off the map because I'm in charge and your a pissant compared to me.
All this type of thing or here's 20 fireballs because you killed a wraith on my little level 2 fief I was holding because you were trying to complete your liberate quest..
Let's get real here folks if those examples ain't bullying then nothing is.
