I don't know for certain, but moderators (on a company Discord) are likely random people in a 3rd world country that are payed peanuts and that is their only income. If higher ups tell them "I don't want to see the Microslop word anywhere" they just do it.

You should be angry at the higher ups that instead of saying: "maybe they are right and we can do better" they decided to hide the problem through censorship. Which, btw, always has the opposite effect of putting what you are trying to hide in the spotlight.

Spamming "microslop" is obnoxious, filtering out childish behaviour is not obnoxious.

But if you don't want childish behaviour, Discord is an ... interesting choice.
