OP didn't mention discord at all. Do you mean my post's parent? They said "because nobody but discord can actually moderate", which is counter to my experience; therefore my post asking for clarification. I'm keen to understand what the moderation tasks are that discord can accomplish that the users who are discord server admins cannot; perhaps I will learn something new, or perhaps I may be able share something I know.

Certainly, as I mentioned, I do see problems with scams and spamming in some communities due to the admins of those communities choosing not to moderate, or not knowing/caring that it is possible, but those problems do not seem specific to discord - IRC also had them, as do other platforms. Hence my confusion.
