changeling reproduction

[Roomba]

If the ling specifically pulls people from the hivemind to create a new ling, then it probably won't be a big problem. Ling victims tend to be a lot more common than e.g. mindslaves, and there are very few people who would lie around going 'ANY LINGS AROUND PLEASE EAT ME' in the hopes of maybe becoming a ling near the end of the game.

E: granted, there are totally people who would do that, but chances are they would have otherwise suicided anyway and the ling would have eaten their corpse regardless.
