Is there any list of banned words on Lemmy)? I'm curious what the removed words actually are.

The banned words are ****, ****, ****, ****, ***, ************, and ***********

every instance has its own rules.

Theres a list of words Chinese media can't use. Most of it is pretty standard. Literally says you cannot use terms like "cripple" and "one eyed dragon" to describe a person. How to properly describe leaders, and a lot of basic things.

I found this section interesting:

1. For persons in the art and literature field, do no use terms such as "movie king 影帝", "movie queen 影后", "superstar 巨星", "celestial king 天王". Normally, use instead "art and literature field person 文艺界人士" or "famous actor/actress 著名演员", "famous artist 著名艺术家," etc.

Your instance rules apply to you, so .ml, as do the instance rules of the community you're posting on, so lemmy.world, and finally the individual community rules also apply. If you do not follow rules of third party instances it's possible you will be banned from those instances, but if you're okay with .ml and .world at the same time then I doubt you'd stumble upon many other issues outside of state censorship maybe as someone mentioned for Chinese instances.

That should be instance dependent

Probably starts with N

Rule 5. Locking.
