Consequences of Inactivating Accounts

We currently have few inactive accounts and I'm looking to clean up the database, but want to make sure I understand any and all consequences of inactivating a given account. I know inactive accounts are read-only, show up in a constituent search, are automatically excluded in List Manager and automatically included in Extractions unlessed manually suppressed. To save me having to check every standard Tess report individually, can anyone confirm for me whether inactive accounts are handled the same in all reports, or if some include and some exclude them? I have not been able to find that answer anywhere. Thanks!
