Sounds like you are extremely traumatized by this.
I don’t think this is a horde issue, it’s a people issue as this happens on both factions 
When you do things in the game that cause inconveniences for other people, they don’t like it and often react emotionally. Can’t really blame them even if it’s part of the game and fair and square based no their war mode setting.
Some folks from both sides (the griefed, and the griefers) actually get so emotionally invested in it all they come onto these forums and create topics to express themselves.
Can you imagine!
Anyway take care
