Dunno if this is considered abuse but it is a total dick move...I think you had to have pissed them off enough to do it tho.

Bad blood can happen these days since many aggressor KDs that wave ghettos looking for war tends to be heavy-handed in their hostiles unless they have a strict wave plan that don't drag hostiles out past 6-12 hrs if the defending KD doesn't want to war.

I don't the history between these two KDs but usually this is where allies/alliances used to be most helpful...to come in and beat up the KD interfering in 1v1 wars

I guess people have to learn to play nicer with each other or else expect to be shatted on if you shat on others.
