During that time period, there were lots of mentions of "runners", "jumpers" and "smart ones" so you may be right. However, I'm not entirely sure if I'm right with this theory, but the mention of the runners, jumpers and smart ones seemed to disappear once the little ones first started appearing.

Maybe, if my theory about Samantha and others being impregnated by Ink thus giving birth to the little ones is inaccurate, then maybe there has been some sort of cross-breeding going on - and the reason why some people are captured/taken is because of some quality in their genetics which aids the procedure. Datu was bitten, Tanya was half-bitten (Saul is too badass to turn into a biter) - maybe that is Ink's way of gaining control over those individuals whose DNA/genetics are important. Obviously he can't have these people held prisoner anymore since the Arena was destroyed. A tactic change on his behalf perhaps?
