Perhaps a simple way that you could communicate with each other without seeming like a 'faction', is to post your image rather than namefagging. I've noticed "KB" posts his little Bee image. I think it is subtle enough that most anons won't catch it, but those of you who happen to be posting in the bread will catch it.
Of course your outside infiltrator guy will catch it too, and then start bitching about it. But we just think he is a shill so he gets ignored. He does a good job of painting /comms as evil, so don't give him ammunition is what I'm saying.
Thanks for listening, it gives me some hope.
