Did you read my post? I said that my faction's size right now is not final. Also if you guys are insular and not very connected then that makes pillaging and plundering not too hard since there wouldn't be any alliances. Also my faction will trade if it makes a good profit.

Insular societies =/= no alliances.

What we are saying is that species and cultural contamination is not likely to be strong enough in this setting to warrant a collective criminal underground. Political and military alliances are in no way held back by the same factors, though.
