No idea about those, though I assume that the Reapers just killed them because they weren't needed and that the Reapers don't like "lesser synthetics" because they aren't perfect like the Reapers are. Though I suppose there can be Corrupted Geth, geth programs that have been permanently bonded to Reaper-made hardware.

But this blog's about making your own Reaper minions.
