Server as in individual communities, look in Community settings on Discord > Safety > Regex.
Take a look at that, that's how it works.
I don't think you understand Automod.
I have used it in discord, yes. I was just confused by your usage of "server" instead of "community", since they're two vastly different things.
EDIT: That means that your original reply doesn't answer the denial of service issue though, but I suppose @TheKodeToad answered that well enough.
