Do you rename Sims? Particularly non-played Sims?

I will rename & change looks of sims if cheats to create my own versions isn't available (this was something I did with the Get Famous expansion pack at first for different directors/make-up artists/stylists/etc.) If I can create my own via cheats or anything else, I will get rid of the computer generated sims (either by deleting or plopping in my cemetery lot specifically to kill them off).
