Do you rename Sims? Particularly non-played Sims?

There were so many I couldn't pronounce! It felt like too much work to go into CAS for ALL of these families and rename them. So when I downloaded MCCC, I just deleted the families with names I didn't like. I thought MCCC would just replace them with other Sims with more normal names.

It did sometimes, but I felt like I kept having to delete so many Sims. Eventually I just downloaded ALL of my houses off the gallery and I set MCCC not to allow homeless sims to move in autonomously.
