Do you rename Sims? Particularly non-played Sims?

I used to but don't really bother anymore. I play rotationally so I have plenty of sims of my own to look after. I give make overs to townies my sims have became friends with and once in a while I also go to manage households and remove households that share the same name... I know it's futile since the game keeps generating new ones with the same names(!). So yeah I would be better off with editing their names instead but they just annoy me too much.
