So this just happened to me as well. Hundreds of messages being spammed in every discord channel, and there is no ban button because it's an application, not a user. Banning the user who started it does not immediately remove the app or its messages either.
Thankfully in my case there was no CSAM involved, but it easily could have been. Either way it's still annoying to go through every channel and remove hundreds of hateful racist messages one by one.
I was unaware that this feature even existed til yesterday - apparently this has been as issue for a while now, but I don't spend much time browsing social media and missed the memo. This might be old news to some of you.
For the rest of you:
Server settings > Roles > Default Permissions > (scroll all the way to the bottom) > disable Use External Apps.
That feature defaults to Enabled ever since Discord introduced it and is easily abused.
Yesterday I got a massive cyber attack on my discord server, thousands of (obviously illegal) CSAM were dropped and myself, mods, and any other unwilling viewer were exposed to this.
The worst part is Discord moderation COMPLETELY FAILED. I couldn’t ban the attacker because it was an “App”, so I was forced to manually lock every channel in my discord to prevent any further harm. When I got to the last channel I was informed I couldn’t private it because “it’s against community guidelines to not have a text channel open to the public” MEANWHILE we were HELPLESS to stop the attack because of this.
Discord claims they’re making recent changes because of child safety? What a joke. They can’t event prevent unapproved 3 day old app on their own platform from distributing CSAM.
I’ve been a 8 year nitro user, I cancelled it last week because of the P*lantir connections. After this I’m looking completely for a replacement. 🤬
Discord if you want to make it up to me, start by getting these App creators involved with this attack arrested. Yes I submitted a report.
