I got a similar reply from a mod account (I forget which subreddit) because I used the word "crazy." Got linked to this list: https://www.autistichoya.com/p/ableist-words-and-terms-to-avoid.html

Bots on reddit are just so universally annoying and most of them provide no value at all. Most of them should have been banned on sight anyways.

I suspect if you are trying to build an inclusive community but don't have a lot of diversity already, the only thing you can really do to change the culture is to remind people to be considerate in the way they speak. And if most people who would be offended aren't actually part of the community (but you would like them to feel welcome to join), then you might want some bot rather than a person to be the “narc” and remind people to be on their best behavior. So I guess if the mods are the only ones who want to be nice, then yes, it is a bit ridiculous because it will never work. Even if people change their language, they won't be nice. But if most people want things to change, it could be a helpful way to both remind you to be inclusive and get the few people who would rather talk about how having to say bartender is censorship (without actually defending why they want to make a point of saying “barmen”) to realize that they either have to change the way they talk in that particular community or find a better fit.
