This is about way more than just your gang bud. Please don't take this so personal.
This isn't a witchhunt, the point I'm bringing up also hurts gangs I'm friends with but I can't blame them for abusing the system if staff refuse to enforce it.
But no, at risk of dragging this off point, members of your group helped aegis in their fights when they were losing, and aegis helped you when you were losing. The only active aegis players that actually log in anymore typically run in your group 24/7. That is cheating. People have been banned for that same thing and had bases removed from their gang.
But at the very least, Aegis could at least wage the defense that they, sometimes, exist independently as a gang from CnT. BBC does not. BBC only exists for the singular purpose of abusing game mechanics with wars, and skirting rules with gang bases and turfs.
