Minor wording change!

Hey Darius!

Always loved this repos, but as I was revisiting it for a new bot, I had the realization that if you were to make this today, you'd probably do a few minor things differently with naming, eg using banlisted instead of blacklisted.

No sweat if you are too busy with other stuff or if this would cause a whole bunch of problems for people with code in the wild, just thought I'd leave it as a note!

The issue names no file, test, or entry point. Start by searching the repository for “blacklisted” and related naming, then confirm the intended replacement and its compatibility with existing users. Done means the maintainers have agreed on a scoped wording change and all affected references are consistent.
