Not to mention that "their people" may only be a subset of their allies. I don't belong to any player groups, but I still do BGS and even PP on occasion. In BGS, I tend to side with the underdog against these crazy-big PGs that think they own the galaxy. But I rarely broadcast that I'm helping, I just pick the faction I want to support and run INF missions, etc. Now if I were so inclined, I could employ a bot army to this end, and nobody would know it's me but me. This assumes these bots are real and not figments of people's imagination.Its like the open only powerplay topic, where every power leader swears blind that all their people are in open, its the other side that is hiding in PG/solo.
Disclaimer - just because I could do something doesn't mean I would do something. I don't care enough about BGS to risk getting banned from ED, so I won't be using these bots. Heck, I don't even want to install Dr. Kaii's graphics customizer, because I'm extra paranoid about installing 3rd party software, and a bot capable of driving a spaceship is just as capable of stealing my passwords! Instead I'll play Space Engineers (go ahead, drink) where building bots is a feature rather than a bug
