Certain posts are held for mod approval depending on content. We don’t “filter” in the sense that “you are not allowed to use these words”. However, the terms in question are most often used in derogatory or inappropriate posts that go against our guidelines by new users, so we hold those posts for moderation until a mod can confirm that the use case is appropriate.
The list is not long, and is subject to change at any time based on the types of disruptive comments we deal with. Mods approve valid uses as quickly as possible.
No one needs to see that.
