You should read the Lemmy Code of Conduct, which I am not bothering linking to because you should have already read it. The answer to your question is there. You can be banned, but if a mod bans you, there’s a time limit on the ban. Mods can, however, ban you for a very long time. Using that slur on Lemmy would probably inspire most mods to delete the comment or post you used it in and not much more, unless you come back and repeat the offense. I’d also like to ask you if you have the intelligence to find and read the Lemmy Code of Conduct for yourself. It’s quite clear on this. Also, I would also like all people who take the time to read my comment to know this: Lemmy is not a magical alternative to Reddit. People on here insult each other in comments and it’s sad. I’d like to know why people can’t calmly discuss any topic. People on the internet use slurs for topics of conversation as diverse (and apparently innocuous) as cross stitch and baking blueberry muffins. Why? Anonymity. Why are people not holding themselves up to better standards when they are anonymous? These people could be working in the cubicle (or dungeon) next to yours, every day, nine to five, and you’d never know what kind of real person they are and the attitudes they keep to themselves only to unleash said attitudes with anonymous abandon on the internet. This guy or woman could be your cousin, husband, wife, grandpa, grandma… It blows the mind.

I mean, it’s a slur and you shouldn’t use it, but you can’t effectively be banned from all of lemmy. One or two instances might ban you, but there’s no central authority here.

There are no unified “Lemmy” rules, apart from the instance rules (for example, lemmy.world), that could define allowed language. In fact, due to federation, your main post might be allowed somewhere but entirely removed elsewhere.

I’ll tell you this much, if you did use this word in any of my communities, on most contexts, you’d be banned.

No one gives a shit here. People use much worse vocabulary, there is plenty of misogyny everywhere and no one even gets a warning. Say what you want.
