Words matter

This was already addressed on 24 August 2017 in #2865280: Find a better name for Graylist → where we found better names and again on 24 and 25 August 2020 in #3149562: Remove legacy terminology from UI → where the legacy names were removed form the UI.
The 2.x branch doesn't have the words you are offended by in the configuration or codebase. But in 1.x it would be a BC break so they remain. If you have an issue with that I would strongly recommend upgrading to 2.x.
This week the numbers are 37,287 vs 26,547 → (1.x vs 2.x) so you can contribute to making 1.x obsolete by upgrading your sites.

I am going to leave this issue open so that I don't have to periodically close them when people don't find the old ones.
