If you blockade a warp point into a system and destroy any colonizers that come through, it will keep sending another colonizer forever.
Ask my allies in PBW, I colonised pretty fast yet I didn't build that many colony ships myself. All I had to do was to put a battery of sats with allegiance subverters on them at warp points. It costs me practically nothing yet I have a constant supply of new colony ships. What's even better the colony ships come with supplies of different atmosphere breathers.
